Only for 1.13 and 1.14, probably works on 1.12 and under but not fully (mainly because of WorldGuard). I plan to restore compatibility with earlier versions on coming updates
Changelog:
Added 1.14 support
Updated to compile with latest Factions, FactionsUUID and SimpleClans versions
Updated a bunch of other libraries
Removed DisguiseCraft support (seems abandoned)
Hide vanished players from /pvplist
Fix 1.14 bug with keep inventory
Some internal changes, should make it easier to update
