Description of the problem

Primordial Malevolence broken on sponge, strange wight teleportation (to blockades), turrets do not shooting and blockades can freeze player/malevolence and lag server. Also, without sponge all works fine.

Unfortunately, this did not help :(

Maybe try setting max-bounding-box-size in Sponge's global.conf to 0?
I've read that this can cause problems with some mobs, but no idea if this is related to this problem at all.
I can do some testing tomorrow if I have time

I've solved this problem by changing max-entities-within-aabb in sponge config to -1 and max-bounding-box to 0, but it would be better to enable auto-populate and configure limit per entity individually.

Thanks! I'll add it to the FAQ/Common Issues
