There is a very strange bug when ppl leave the table and return to main room. the message says bash has joined cork, Negaar, Urh2006 and 34 other people at a table of Main room. instead bash is in the main room. Can it be solved?

It don’t seem like much of a bug, its just telling you someone joined the main room with the rest of people.

but its says free table of main room its strange and a bit funny.

It doesn't say free table, it says a table.

Technically speaking, the main room is also a kind of table, even if it isn't a game. In French or some other languages, for example, you can also chat on the main room. In English this had to be disabled due to way too much abuse.

I would consider this an unnecessary announcement, although it's probably extremely low priority.
I'm also not convinced that this happens whenever someone leaves a table. I think it happens when someone specifically presses CTRL+J to join a player who is in the main room, although global messages became a little buggy in general recently, so my information could also be incorrect.

understood thanks for explaination
