Claiming land crashes server

[Arctiblaine]

So, while asking my staff to claim their respective lands, the entire server crashed. The weird part is, this worked. But now it doesn't. It only works for claiming Safe and War zones, but now it doesn't work at all.

Another issue is players logging in. No errors happen, Factions for Nukkit just has a slight seizure and tells me that it had an issue with players respawning.

Any fix for them?

The first error ill look into. Although the second error looks like you might need to recompile the plugin

Oh goodness. I'm a bit illiterate for a newb programmer. I'll look into recompiling.

EDIT: Erm, turns out /f home also crashes the server.
EDIT 2: Any command to do with land crashes the server. (home, map.. etc)
