MCMT Causing super high spawn rates

[SweatyMemer]

Upon an event, such as breaking a block, a large amount of mobs spawn (upwards of a thousand in some cases). The most common occurence is when breaking a block a huge amount of squids spawn.

This is running with the all of fabric modpack 6, with all optimisation mods removed for compatibility, with the latest mcmt version for 1.19.2, which the server is running on.

I've not looked at all the mods in that pack, but performant and forks of it that alot of packs have cause this. I experienced it myself before realizing I had it installed.
