In theory, you can roll back to a previous version. The database should be compatible, but for the future, I recommend making regular backups of your server so that you can go back to previous versions at any time.
Well that can't be the difference since all use the exact same protocol.I have a suspicion that the TS3 client may be the cause of the failures, since there are no problems on the test server where only TeaClient is used. And on the server where only the TS3 client is mainly used, server crashes are observed. (Server version 1.5.0 beta 12)
Yes, you were right1.5.1 beta 2 is out and contains a crash fix, but I don't expect it to be the one we're all searching for.
