Since the update some of the plugins i use were broken,  such as copy n paste, waterbases  causing saved games to not load upon server restart.

Plugins were all updated and i thought all was well,  now when i restart the server it doesnt load, cant load the save file and gets stuck on the console on
"cSpawning 11491 entities
Database sv.files.237.db opened, SQLite version: 3.34.0
Couldn't find prefab "assets/prefabs/building core/foundation.triangle/foundation.triangle.brick.prefab"
Error loading save (server/mrs/proceduralmap.6000.974815975.237.sav)
NullReferenceException: Object reference not set to an instance of an object
Initializing 16034 entity links
done.
Initializing 530 conditional models
NullReferenceException: Object reference not set to an instance of an object 

and then the server does nothing and just sits there,  i can load and unload plugins but cannot get past this stage, i then have to wipe
to get server to load again.

Not sure which plugin may be causing it, a conflict? or something im missing,  any ideas?
