/p clear has trouble with custom biomes

Server Implementation

Paper

Server Version

1.19.3

Describe the bug

When I try to clear a plot that has a custom registered biome with Volans (or any other custom biome plugin), errors happen in the console.

To Reproduce

1. Create a custom biome using a biome plugin
2. Use for example /p setbiome $volans:blue (normally: /p setbiome $yourplugin:yourbiome)
3. Try to clear the plot with /p clear
4. Wait for errors / result

Expected behaviour

It should remove what was build on the plot, maybe also the custom biome, but you could always override the biome with /p setbiome forest. It does unfortunately not work for this case, as the backup process became stuck and overriding biomes only helps for the /p clear process after a server restart.

Checklist

• I have included a Plot debugpaste.
• I am using the newest build from https://www.spigotmc.org/resources/77506/ and the issue still persists.

Anything else?

I am not sure if it is 100% a plotsquared or a FAWE / Worldedit issue because there are different problems mixing in together

Start by reproducing the failure with /p clear after setting a custom biome via /p setbiome, then inspect the linked error log and Plot debugpaste. Compare the clear and backup behavior for custom versus standard biomes. Done means clearing completes without console errors or a stuck backup, with the expected biome behavior confirmed.
