i know that, it has been already fixed for the next update. it come from the server list being never refreshed because of a type overflow.
but i think i introduced another bug with the add of a buffer pooling...

[ZetaMap]

mmm no seems to be another thing..... but the crash is also very weird...

commit 45da8c7

incompatible with older server versions (I haven't updated the server yet, only the client - tested)
In this case, it's likely that if you update the server, the old clients won't be able to ping or connect (I haven't studied this yet, but I assume it's true).
when pinging the server or its rooms, the server logs do not display anything (last 5 seconds)

[ZetaMap]

Wait, when I said "check for updates" I mean for latest release, not latest commit. To get notified you can follow the repo or me (as it's me releasing them).
But you don't need be updated to the latest commit as I can break things or made mistakes before releasing.

claj client doesn't work well but the 159 release, which was released more than 12 hours ago, even if 2 players are on the 159 version and use the latest release of the client mod from github, the player will only have 1 player in the room and the connection will be disconnected after

I didn't updated my game rn. What the console is showing?

I went to an open public room to ask the players how the multiplayer works, and to be honest, I didn't understand it either. He said he had updated the mod and had to wait up to 2 minutes to see the rooms. He claimed that this was the case on all servers, but I'm skeptical. It's possible that some servers haven't been updated to the latest release of the claj server. I'll check the information myself later and provide an answer. Otherwise, I'll close this issue.
