Lost Souls from Forbidden and Arcanus are flooding my base from the mob farm. Is there a way to disable them from spawning on Delightful dirt? They don't obey physics either so just pass through all the walls. I have a LOT of them floating around now.

Lost souls were turned off in a later update.

Update: It's only from passive mobs on the delightful dirt that I can see.

The Industrial Foregoing mob crusher will kill them, just be sure to use a large enough range addon to catch them as they float away
