Support_Player_Persistence appears to be causing my own client - and no one else in my dedicated server to stop loading datablocks at a specific point.
I can manage to load into my gamemode if I start it up directly as a non-dedicated, but as a dedicated; if Player Persistence is currently active, my client stops loading a little after the center point of loading datablocks.
Everyone else manages to load into the gamemode fine and all other add-ons / code executed by the gamemode is purely default.
EDIT: Don't really know what happened now, first it was that my server wouldn't run with player persistence, then brick_large_cubes; deleting both and allowing them to redownload seems to have fixed the issue for now...
