When a lot of spambot trying to join server i get this errors spamming in my console.

Janmm14 commented 6 years ago

Spambots apparantly send wrong data and so just cause log spam instead of ingame spam.

The proxy is acting as intended, something is sending you invalid data, you're being told that something is sending invalid data.
