the problem is similar to #328, but I have mod version 1.1.4 and forge 47.2.21 and I still have the problem.

I'll attach a few screenshots with my entity count


(loaded entities are now 780+ and never decreasing)

This happened after we explored some more caves (Primordial, Magnetic); I can't even go into water for the abyssal chasm because it puts me on 1 fps
I've tried going into peaceful mode but that only reduced the rendered entity count

P.S. I added worldedit and spark recently to try and find the issue, I haven't started the server with these mods just yet
