I am using BigReactors with 11 other mods in a stripped-down version of Attack of the B-Team (the full pack lags too much and I don't really use all of the mods) and when I try to launch the pack, it crashes and gives the following crash report:

---- Minecraft Crash Report ----
// Don't do that.

Vec3 Pool Size: ERROR NullPointerException: null

I checked the source code (I know a medium amount of Java, but I'm no expert) and the problem seems to be that codechicken is trying to get to an array entry that isn't there. I'm using Codechicken 9.0.9 and BigReactors 0.3.4A2 with minecraft 1.6.4. I hope that I didn't bother you with a personal problem and I think that it may be an issue with BigReactors and other mods (Witchery has been picky with me in the past) not playing nice, but I hope you'll take the time to help me if it is just a personal problem. Thanks in advance!

It looks like you installed BR and assigned it an ID range overlapping a removed mod. Change the BlockID for multiblock glass and the crash should go away.

Yep, that was it. I changed the ID and it worked just fine! Thanks so much!
P.S.- I called it, it was Witchery.
P.P.S.- that was a really fast response...

I'm having the same error as the user above but I can't find anything in the config file called multiblock glass. In fact, I can't find any item IDs for Big Reactors. Is there a separate config file that covers that and isn't found inside the Big Reactors folder in the config folder.

.?

If you use 1.7, then there is no id config to worry about.
If not use 1.7 to prevent this issue.

Okay, thank you.
