Bouldering Zombie Spawning In Base

[stuwwmm]

Installed the mod today on my server but it seems like the mob known as Bouldering Zombie is spawning frequently inside my base even if it's light proof. Is there a way to fix this or disable the mob from spawning at all?

this has been happening to me too. my base is lit up like 30 blocks all around it but theyre still spawning everywhere.
