If a submersible captain is logged out anywhere other than the correct FC house, AutoRetainer does not handle this in a reasonable way. The character is excluded from retainer multimode, even if it's near a summoning bell. The character is not excluded from captain multimode. Multimode is then disabled entirely, stopping all plugin operation. A more sensible behaviour would be for the captain to be excluded from captain multimode, and for plugin operation to continue.
