I'm having a similar issue with the ICBM mod, whenever I try to place down an explosives block. It was working fine in CQR v 1.12.2-2.1.3B.

The latest update (2.6.3B, Forge 14.23.5.2860, MC 1.12.2) seems to have a HUGE conflict with the ICBM mod and a few others. Whenever I try to place down an explosives block from the ICBM mod, the game crashes. From what I can make out from the crash log, it seems to point the finger at CQR's "sayNoToPlacingBlocksNearBosses" event handler... even though I was nowhere near any dungeons.

I can post the full log file if you need more information. I'm hoping that this can be patched, as I use the ICBM mod quite frequently to destroy dungeons once I have completed them (or as part of an artillery barrage before charging in to fight the boss). Not being able to use it anywhere any more would really suck - I don't want to have to give up either mod. It might be worth noting that it was working just fine with CQR before I updated to the more recent versions (I was previously on CQR version 1.12.2-2.1.3B)

the problem here is not cqr but other mod's returning null for things cause they think this is funny or something.

Anyway, we have a fix for this but it does not have priority for us.
Temporarily you could disable that certain feature in the config, that should prevent the crash.

Patched in v2.6.4B
