[BUG] Player is disconnected when the host selects a song

[dotMortis]

Your Platform PC Steam

Describe the bug When the host picks a song, there is something like an 70% chance that a random player will be kicked out of the lobby. The player is kicked right when clicking on a song.

We were a group of 3-4 players

Do you have logs?

I have the same problem. My logs: https://img.bymarcin.com/2020.11.18.18.45.36.log https://img.bymarcin.com/2020.11.18.19.43.59.log

For anyone who has this issue in the future, update to the newest version. The kick is caused by an incompatibility between the two versions.

@Goobwabber Thank you. Is it possible to check the plugin version when joining the lobby and display a warning when the host is on a diffrent version?

[Goobwabber]

Yeah, that will probably be added in #53

[jklpuzo]

we have the same version but still have this problem from time to time. I would say 20% chance of being kicked.

@Goobwabber Had this issue again, both clients have exactly the same plugins + versions (everything up to date). The same Song worked correctly the second time.

@Goobwabber It happens much more often when I'm not playing locale multiplayer.
