I am just letting you know - for now I am going to avoid this mod.

I'm assuming you are talking about a dedicated server and latest 1.19.2 of forge (43.2.1). I don't see any problems. If you are using a mod pack then could you post the name, so I can try. Also, add any other info that might help identify the issue.

Its my personal pack but after I removed this mod it stopped. Um I am working on some fixes but if you want to test for future proofing here. https://www.curseforge.com/minecraft/modpacks/fiction-friction

To confirm, does this mod cause a massive drop in performance/(increase in memory usage)? Thank you.

I didn't see a problem with just this mod. I'll, at some point, test it with the above modpack.
