### Testmerges

#8442, #7645, #8470, #8378, #7895, #8554

### Round ID

26580

### Description of the bug

### Specifically on Beta 516.1656. Didn't test if it's present on other 516 versions. Seemed not present on 515.1647
Maybe I'm just impatient but I waited about 1 minute for it to do something.

But if you're in the lobby and use Fix-Interfaces for... some reason you now need to reconnect.

### What's the difference with what should have happened?

Lobby menu thingie should pop back up. Refresh TGUI also doesn't seem to get rid of the please wait.

### How do we reproduce this bug?

1. Be on Beta 516.1656
2. Join Server
3. Immediately use Fix-Interfaces for some reason
4. Cry?...
