I've been running Actually Additions for a long time and never had a crash until today. I'm not seeing other mods in the list so I'm posting it here: https://gist.github.com/bondgb/6b21cbcf8d5ca6351d6c5d5b1acc75a7

It could be related to another mod though, as I've just added Minecolonies and updated Recurrent Complex to test it.

This crash should already be fixed with one of the last few commits, so it'll be fixed in the next update! :)
