Exception: GameProfile name and skin name do not match.

Since updating citizens I get the following exception

[05:04:48 WARN]: [Citizens] Task #465 for Citizens v2.0.22-SNAPSHOT (build 1503) generated an exception

Can you post the npc savedata for that NPC?

Looks like the user had name jacobus7 when the skin was saved, but later renamed to xTICEx, and since the skin still has the user saved under the old name but is aware of the new name it got confused somewhere along the way.

I guess the question is when to expire the cache.

For now I have changed the exception to a debug message. Need to see what impact that has.
