Issue since the last update - Arena enemies not spawing/attacking

I have done a lot of isolation testing to see if it's another mod but i dont think so

Since the last update to modthatisnotamod a few days ago, in Arena - Fantasy arena with mods loaded, after beating wave 1, either new enemies do not spawn or they spawn but don't advance towards you. Thinks work fine with no mods loaded (vanilla). This is on brawl mode.
