If anything breaks, check if it is still broken without TickThreading
We don't want to annoy mod devs with issue reports caused by TickThreading.
Seriously, please don't.
If it's only broken with TickThreading, report it at http://github.com/nallar/TickThreading
 
Also, you really should be making regular backups. (You should be doing that even when not using TT.)

Can you tell what is causing the problem? I really need to fix this.
Click to expand...

Can you try disabling world unloading?
 
It happened even after I disabled world unloading. Sometimes it happens when I am not even in that world.

If anything breaks, check if it is still broken without TickThreading
We don't want to annoy mod devs with issue reports caused by TickThreading.
Seriously, please don't.
If it's only broken with TickThreading, report it at http://github.com/nallar/TickThreading
 
Also, you really should be making regular backups. (You should be doing that even when not using TT.)

If anything breaks, check if it is still broken without TickThreading
We don't want to annoy mod devs with issue reports caused by TickThreading.
Seriously, please don't.
If it's only broken with TickThreading, report it at http://github.com/nallar/TickThreading
 
Also, you really should be making regular backups. (You should be doing that even when not using TT.)

Fixed in latest, you can re-enable world unloading.
 
Nallar we installed tickthreading last night. We had serious tick rate issue and was down in the dumps. Upon installing tickthreading there was a day night diff. We trying to crash the server, multiple TNT flowers etc. item bombs u name it. This mod is GODLIKE. It is the I WIN button for server admins. You sir are my hero.
 
Thank you very much Nallar for the work you do

I was wondering what version of CMCP + you use for your mod

I use MCPC+ L15 with an old version of TT (TickThreading-1.4.7-1.0.0.1678.jar)

When I try to update TT or MCPC+ or both I tried several combinations

IC2 machine always changes orientation and face the ground when im going to another dimension other than DIM1 DIM-1 ex:mining

I was wondering if you have any advice for me

im using multiverse

According to the MCPC+ devs you should always run the latest possible version of it, much like Tick Threading they are constantly fixing bugs and adding performance improvements.

Also 67 is last build that is being released from the MCPC dev team (there is now a fork that is going to keep going but I don't have the link, found it then lost it) Just before you update your going to need to change your mystcraft worlds over to the new file system or you will be really confussed.

I'll keep my build MCPC+ L15 and TickThreading-1.4.7-1.0.0.1678.jar IC2 works well with this combination
 
The AuraWorldTick with Thaumcraft is not fixed due to it happening on version 1943.
Am I the only one getting this error?
 
v.1.5.2

Haven't heard if the 1.5.2 patching is working or not, so I went ahead and gave it a shot to see what would happen.

I am using the latest MCPC+ build as of today, as well as the current build of TT as of this thread ( mcpc-plus-1.5.2-R1.1-forge738-B582.jar / TT#32)

After erroring out, I disabled all mods, all coremods, all plugins, deleted the crash report, restarted and installed per the instructions (easy) and the below is what I got after patching, then starting the server.

Thanks,
 
Disregard my last comment, sorry guys. For some reason i was thinking those builds were MCPC+.

[Edit] I believe Build#30 does reference MCPC+ compatibility (I knew I read that somewhere). :)
 
I tested this out and found a really annoying bug, it unloads chunks loaded by other chunk loaders from time to time.

And I dont want to delete this awesome mod, its to great that I want to stick with it whole my life :)
Great job.
 
just stumbled across this, absolutely stoked to see this in action for 1.5.2. Tired of a simple pipe setup or even just a few armor stands and shelves causing massive amounts of lag. Also impressed that MCPC+ support is a priority. That server software combined with this seems to be a complete gamechanger. Isn't this what mojang hired those bukkit guys for???

Anyways, just showing my support.
