Hello,
Firstly, I am posting this here because the crash report I got says to contact the coremod authors first. Also, I am not sure that this mod has anything to do with the crash, but better safe than sorry. That said, here is what happened:

Leading up to the crash, I am trying to place maps inside of Bibliocraft Map Frames. However, it seems as though just holding the map can cause the crash. My crash report can be found here.

I will also be posting this with the authors of the other coremods I have installed just in case.

This has nothing to do with CTM.

In the future, just try removing those mods and reproducing the crash, there's nothing in this log that points to us.
