Looks like a player's Last Seen Date might be null. But I'm not sure where this comes from. Any thoughts?

LordTylus commented 3 years ago

The last seen date seems fine. My assumption is the identity is null. - Meaning the owner of the grid is a no longer existing playerid.

I assume this hapoed due to the use of identity deletion like sandbox clean or identity purge.

Or keens own identity purge. Likely other plugins will have problems with that grid as well.

I can just skip the grid in this case I guess.

kippandrew commented 3 years ago

Any suggestions for how to identify the grid?

Sadly couldnt reproduce it with your world as it somewhat fixed itself.

but I fixed the most likely scenario where this could happen in v1.0.6.4
