Item IDs

[Cosmology27]

So I'm messing with junk, and I'm finding lots of item ID conflicts, which don't show up in the ID conflicts file. The game will still run, but lots of recipes and stuff are WAY off for some things.
Here's an example of the log registering a conflict. Other item ID conflicts are easy to find, because it actually gives the correct item ID. Others aren't given the correct data, beacuse I'm not finding those items, either in the NEI or in any of the cfg files. For example, the 540 conflict (see below) is an item that isn't listed in the NEI or in any cfg files, so I don't know where the conflict is actually happening! How do I check on this? I've already tried the block name like net.minecraft.item.ItemBlock@64bcc4c2.
I've also tried looking for the ladder in the DRPG cfg. Everything I can think of doesn't turn up something that I can change to fix the config.
How do I find the conflict so I can fix it?

Yeah, if it is a block it seems the game will crash & the report gives you the right numbers. If it is an item forge will tell you there is a discrepancy & do you wish to continue when you try to load a saved game. The console log may tell you which mods are involved but the #'s you see may or may not be the #'s in the configs.

IDfix minus...


That mod is all you need to know.

You may still get some conflicts with mods that are temperamental with ID's or mods that have their own ID resolution methods but it will decrease the conflicts by at least 90% if not 100%.
For example Artifice has a built in ID resolution method where you specify the start of an empty range and delete the current ID's and on the next startup it fixes it but this unfortunately clashes with IDfix minus.

Edit: also after it's done it's thing you may want to disable it.
