Nothing got added during a runtime and it could be the database but most likely a corrupt playfield or corrupt process id.
Multiple PFs are bundled in one process id. If one of them is corrupt, all playfields sharing this ID in the process become corrupt.
Something that won’t happen in HWS+, cause I have the knowledge to give each playfield its own process.
In RE, because of the insane amount of playfields, this is not possible.
So, a server restart hopefully fixes it like here
