Describe the bug you're experiencing

My Forge server didn't even start without the mod, I don't know if it's the mod's fault but items dropped on the ground don't appear but they still exist and can be picked up, you just can't see them and they don't appear on the minimap, this isn't client side since items appear normally in singleplayer.

Reproducability

Start a server with the mod and drop and item.

Mod up to date

I closed the issue because I added a few more server side performance mods and the problem seems fixed now, on the other hand now some other entities don't have visuals like Botania's Terra Blade beam, and Cataclysm's Incinerator's Right Click Attack.
