i get this error when finishing loading the best of both skyblocks (or something like that) modpack on curse/ftb launcher. it is a mix between beehappy agrarian skies and skyfactory in one.
this is the crash report. and now i will post the log.
and the console (if the log is different than the console):
EDIT: just learned to use the edit feature. also, this is my first post! thats all i wanted to say. so sorry if i missed something!
An enchantment conflict is occuring between Draconic Evolution and VeinMiner. Try going into the configs and changing the ID of the Reaper enchantment from Draconic Evolution to something that may not be used, like 999.
