Game crashes if you switch worlds too fast

[zjavierf]

If you leave one world and join another straight away the game will freeze, not respond and force you to quit the game and reopen it.

This is most likely caused by one of your mods being incompatible with the "Allow multiple running Worlds" option.
Please send a list of your mods so I can figure out the incompatibility, in the meantime you can set "Allow multiple running Worlds" to OFF.

Okay I'm fairly sure this is an incompatibility between Fast Backups and the "Allow multiple running Worlds" option, could you confirm a couple things for me?

1. The issue also happens with only FastQuit, Fast Backups and their necessary dependencies installed.
2. The issue does not happen with FastQuits "Allow multiple running Worlds" option turned off.

If this fixes the issue i will add Fast Backups to the list of mods that automatically disable this option in the next release.

Testing with a fresh instance of 1.21 Fabric 0.16.7
Mods:

Cloth Config V15 15.0.140

Fabric API 0.102.0+ 1.21

Fast Back 0.19.0+1.21-fabric

FastQuit 3.0.0+1.20.6

1. Can confirm the game still stops responding and forces you to close when loading a new world whilst another is saving. (This
   was repeated 3 times to make sure)

2. The issue is fixed with the "Allow multiple running worlds" option is toggled off.

3. And to make sure i removed FastBackup and renabled "Allow Multiple running worlds" and the issue does not occur.

Thank you for testing, will be fixed in the next release, for now just disable "Allow multiple running worlds"
