1 year ago Is your server running in offline mode and allow players with nonstandard usernames? Mojang specifies that minecraft usernames adhere to the following format:
- they are between 3-16 characters long
- they allow only '_', '0'-'9', 'a'-'z' and 'A'-'Z'.
The offline player tabcompleter in InvSee++ assumes that all usernames adhere to that format, so if they don't, that can cause issues. I will address it by not tabcompleting invalid names.
