When i play with mods, and i use the downfall mod, it works fine for the most part, but i also have the hermit installed, among a few other modded characters. i've only seen it with the hermit, but when i play as any of the bosses in the downfall gamemode, and i get a modded boss, such as the hermit, the game crashes when i click on starting the boss fight. it works fine with regular characters as the boss, so i would assume its a problem with mods. i can give more important details if needed, i just dont know what would be important to say here.
