grimac version 2.3.66
mc 1.21

Floods console whenever someone logs in to the server error.txt grimac version 2.3.66 mc 1.21

That's a separate issue, another packetevents error, and reproduce without plugins.

and what about the problem what I reported?

[SamB440]

Should have been fixed by packetevents.
