i dont know how to fix that

Die Mod Enemy Race Manager (1.4.2) hat einen Fehler verursacht, der nicht behoben werden kann.
Bitte informiere den Autor der Mod über diesen Fehler.

Error while running event enemyracemanager::on_nth_tick(30)
Unknown entity name: erm_vanilla/bob-spitter-spawner/2
stack traceback:

I think bob-spitter-spawners is from bob's enemies mod.

You'll have disable bob's enemies mod for this one to load. This mod doesn't compatible with Bob's Enemies mod at the moment.

Worked
thx
