I've been working on a modpack and both Charm and Mowzie's mobs are installed. When loading the pack, they both throw an error related to the GUI. I've seen other installations wherein these mods function side by side, and I've reinstalled them both in this pack. When Charm is removed, the pack loads fine, as it does when Mowzie's Mobs is removed and Charm is left alone. Is this issue an interaction with another mod, or something else?

Is this issue still happening?

Not certain but this might be fixed for the next release. We’ll see then.

Thanks for responding, are there any mods I could remove in the meantime to fix the problem temporarily, at least until the next release?

You mean besides Charm? No, highly unlikely, sorry.
