On launch it crashes and a produces in the log: Caused by: org.spongepowered.asm.mixin.injection.throwables.InjectionError: Critical injection failure: Redirector netherexp$modifyArrowVelocity(Lnet/minecraft/world/entity/projectile/AbstractArrow;Lnet/minecraft/world/entity/Entity;FFFFF)V in netherexp-common.mixins.json:item.BowItemMixin failed injection check, (0/1) succeeded. Scanned 1 target(s). Using refmap netherexp-common-refmap.json
I.E I think the mod is incompatible with survive due to the fact union lib is a dependency of survive

UnionLib's code is not open source meaning I cannot figure out if it issue is being caused on my side or theirs
for now I'm going to mark this as wontfix but you should report this incompatibility to UnionLib as well
