[1.20.1] Concurrent modification spam

[SaloEater]

That's probably more of a suggestion since no one has complained yet.

I am honestly very confused by this, but some of our player have their log spammed with this. When I try to replicate their environment, it's all fine for me, even in multiplayer, so can't even provide any steps to reproduce that
