Just as the title says, I can't open any world in my modpack. Crashlog points out that there is something wrong with BetterNether. I've made a post on MC-forum just in case before that, but it was about Colormatic. I've stumbled upon Vanadium as an alternative, but the error seems to remain here as well. Is there a way to fix this issue? Maybe some config tweaking or something? Thank you in advance.
