Cannot log in to game with one character

While playing maps, game crashed with error:
Exeption
Attempted to resume pathing action with an invalid skill: 2148073472 object: Metadata/Monsters/MudBurrower/BrambleBurrower@68

Now every time I try to log in to the game with this character I'm having the same error.
No problem with other character. Probably map oriented problem.

Playing on LinuxMint via Steam.
