Fatal error in
Metadata/Monsters/TerracottaGuardians/TerracottaGuardianSceptreAmbush_@32: Number of shared states is different on client and server!
Delta: 42

POE 2
I can't log into the character. Now it crashes with this error when I try to log in with this character.
This happened when my friend summoned terracotta guardians.

same

Logged in after 10+ hours.

This just happened to me also. can't log into my character.

Looks like different monster but I got this too, just playing a map.

My problem went away the very next day.
It looks like the problem goes away when the map is unloaded from the server's memory. The character selection menu will indicate that he is in the shelter.

This just happened to my gf as well. "Fatal error in Metadata/Monsters/TerracottaGuardians/TerracottaGuardianSceptreAmbush_@44: Number of shared states is different on client and server! Delta: 51".

She can't play at all, even tried changing graphics settings from D12 to Vulkan etc.

I've now had this happen 12 times over the past 2 weeks, except with Porcupine Ants (always the same). Not only do I lose the map (because I can't log back in until the instance resets), I am also locked out of the game for upwards of 2 hours.

I haven't seen this problem even acknowledged by the GGG team, though I've seen many people posting about similar issues.
