Factions doesn't start on 1.21.11

[TMCThomas]

Paper version: paper-1.21.11-92 (latest)
Factions/massivecraft version: Alpha-10

Factions doesn't start on minecraft 1.21.11, it works fine on 1.21.10. Interestingly it does start when you remove the mstore folder and let it generate a new one, though massivecore still throws errors later (see error 2) I've also tried to remove all other plugins which didn't make a difference.

No rush though! Just wanted to let you know!
Very gratefull that the plugin is still being updated!

Greetings Thomas

@TMCThomas Hey there, so sorry for the delay!

Yes this was due to a change Paper made with the way it used Gson (this is a Google library that is used by all the MassiveCraft plugins) and how it exposed that to plugins.

I had to do some refactoring of MassiveCore to fix this. I have had a build for a few weeks but it was in testing by one of the servers using this new version of Factions.

I just released this officially though as the server doing testing for me has not ran into any issues.
Check out the latest Alpha-11 release though and let me know if you run into any issues!

Thanks for your continued support! 😀

No problem at all! Thanks a lot for the update! :D
