Not sure if it was like this before, but I remember that the plugin was spamming the admin's chat about raids. Now I can't see anything while hearing explosions happening around me. How I can fix this? Nothing changed in my config.

Have you updated to the latest version? Chat notifications seem to be working fine on my end.

Yep, I am with 2.1.1... Maybe it was explosion without raid event linked with it and destroyed object or idk... I saw someting in my F1 console but chat was emprty. Anyways will see if have issues in the future might be ok.
