We have the same thing. Please write to Discord, we'll try to figure it out together.

@Geez I ask you to help with this problem, we are at a dead end and cannot figure it out without the help of developers. Perhaps you have encountered something similar and can tell me in which direction to look?

@AlanoItaliano Can I ask for your contact information to discuss this problem? ideally discord

i am running Omega Manager too

@AlanoItaliano Greetings. We managed to significantly reduce their number, although we are not entirely sure how. My friend also has this problem on his servers. There are no cross mods.
The quantity decreased (in my opinion) when we started using cloud storage of items (special mod), and left a minimum of accessories on the server itself.
However, to this day, the root cause is not clear.
