GrimAC warn Message

On my own PaperMC 1.21.4 Server, I just joined a few minutes ago to build a bit. Suddenly, I repeatedly get lagged back, maybe I was actually teleported back by the AC. Just the whole laggy af situation. Lagging back, no longer breaking blocks consistently, things just not working smoothly anymore. This might be on my WiFi tho. Still, suddenly my console gets constantly spammed with a GrimAC Warn message, afair, saying something about a packets check problem and that „entity“ was null. Can’t remember rn, but I’ll be posting the error message shortly. I though that this might be happening because of the lag, but even after I left, messages kept pouring in at the same rate. Keep in mind this was something like 4 messages a second, all being like at more than 2000 characters. I am just confused and would like to pinpoint the problem so I can try to fix it, thanks in advance.
