  • Tech Support section is for getting help with FTB related problems. If there's a repeatable issue that can be labeled as a bug, then please use the issue tracker for the pack or the app at GitHub issue trackers - If there's no repository for a pack that means that the pack is old and/or will not be updated. Bugs for older packs will not be fixed, unless they are critical.

Title doesnt run with any of the recent updated forges

Launcher Type FTB Launcher

Modpack Revelation

Modpack version 1.8

Have you modified the pack? Yes

Link to log file won't generate log

Details of the issue 4/23

I can't update mods, I updated forge manually. but it wouldn't start.

trying to update the mods already within the pack most notably immersive engineering which requires forge 2655

install the forge folder, updated the json in 2 locations. try with any forge version above 2651

started with just changing the forge only after finding out that some of the mods required 2655. so I went back and redownloaded the modpack, only changed forge version. so it isnt a problem with updated mods within the pack, but between forge and the pack itself

Reading changelogs, commit messages and source code.

this was not helpful. people dont put in their changelogs that they tied their mod to a particular forge version. just that it needs a min version such as forge 2655 or above. the problem is that it isn't running with anything above forge 2627. the base modpack, before trying to update any mods.

I can't read source code that well and I do not know what commit messages are. I would really like to be able to update this as about 25% of the mods in the pack have been updated since last release. especially some of the larger mods in the pack.

Perhaps trying to modify a pack that someone else did (and this is a carefully tested and tweaked pack), is not a suitable task for you.

Either start with creating a smaller pack that you know every change in, or wait until the pack is updated.

Just because there's a update to a mod doesn't = that it's a good idea to update, there could be reasons for mods not being updated in a pack. (breaking co-existance with other mods, no apparent reason for update etc.)

If the current version of a mod make something break (bugs), and fixing that is to do the update to a newer version - then you should post a bug report - so that the team members responsible for the pack in question have a chance to check it out - or perhaps reply with why it's not being updated.

this was not helpful.
There's no other way - no magic answer that solves everything. Only way is to do the hard work, checking stuff out (as mentioned above).

The problem is that at least 1 mod doesn't work with whatever was changed in that version of forge. If you can't find a clue in the crash reports and logs, the easiest way to figure out which mod that is is to turn off/disable each mod 1 at a time and relaunch the game. Yes, this is a time consuming pain in the ass that may take days that you would rather spend playing. Once you find it, you'll have to decide which is more important, keeping that mod or updating the other mod you wanted to update. Doable in a kitchen sink pack, likely to break a lot of things in a heavily altered or gated expert mode or quest pack. Also, there is no guarantee that the update only breaks 1 mod.

nah, seems I may be updating it incorrectly. I made the forge folder basically following it's existing folder as a template. put in the forge universal file. and updated pack.json in 2 places. that is all I can find on instructions for updating the forge. started it up with 0 mods. and it just goes back to the launcher. no log files even generate. not sure what the hell I am doing wrong, and I am enjoying the modpack. I just want to update 32 mods and then possible add in Thaumcraft

made it post the console to a notepad. only copy pasting relevant area after I tried to launch.

ok, got it running.... in curse, not ftb launcher forge 2655

removed advanced rocketry, embers, roots, reliquary, rustic.
updated botania as it threw an exception error

finally got all the way loaded. starts a game mostly fine. a few recipe errors due to embers being removed.

iirc twitch launcher has option to change forge version, if not you should use a launcher which support that instead of changing files manually.

it does. but still had to do the above to get the modpack working with the newer forge. after removing the above mentioned mods and updating botania. worked perfectly. then I updated the rest of the mods and added to it with no problem. thaumcraft works well with it btw. thanks for the guidance. it was helpful. hopefully it helps the mod pack owner see what needs updating or repair. but again, could only get it to work on twitch.

I have Advanced Rocketry ( 1.4.0-80 ), Embers ( 0.230 ) and Roots ( 2-0.104 ) on Forge 2673, so you can probably add those back in if you want.

It would definitely be nice if more mods had recommended/tested forge versions listed. I can understand why they don't have exact required/non-compatible versions though. They will usually stick with a specific forge version, until it doesn't do something they want, then update to typically the newest release version. They don't test each version in the middle to find where things went from not working to working, and they usually don't test forward to see if it will work there either. However, they DO know which version they themselves use, and often learn certain trouble versions that don't work. It'd be nice if they had that information listed somewhere easy to access. <shrug> It is what it is.

rocketry got updated. works with 2655. but using twitch launcher. the ftb launcher for some reason I cant get it to launch or generate a log. personally, I dont like roots or embers or reliquary. too much clutter.

side note. this now works with thaumcraft, electrobob's wizardry, ender io, twilight forest, plustic and roguelike dungeons. having a blast with it.
