Spawners got corrupted (duplicated?) after moving server files
Summary
I have moved my files from main server onto a backup one, after some time Mythic started spamming weird messages regarding "Hashcodes collision in spawners"
Then I have noticed in-game that mob spawners spawn more of the mobs at once (which they shouldn't)
After updating to 5.6.1, the issue got so bad, i can't even start my server with MythicMobs.
I opened one of my issued spawner config and saw this (image). The things highlighted in red are names of my other spawners and they are displayed in the configs of absolutely different spawners. All of the issued spawners were made in game using /mm spawners create and /mm spawners copy
! > ISSUE WAS ALSO ATTEMPTED WITH THESE INSTALLED PLUGINS ONLY: MythicMobs, LibsDisguises, ProtocolLib
Steps to reproduce
Unknown - happened randomly after transfering server files to another server (was told on the discord that this should be reported as a bug)
Current behavior
Server can't start because of these errors. (check logs) MythicMobs spawners seem to duplicate randomly. This happens also to newly made spawners, when there already are some corrupted spawners in the MythicMobs Spawners folder.
Intended correct behavior
MythicMobs spawners not duplicating and spawning the intended amount of mobs.

Proposed fixes
Implement an efficient way to restore the corrupted spawners and find the cause of this issue.
