A fellow pirate, @Storm Crow discovered a major bug when deleting paint. If you have a painted ship set as the main, and try to delete a paint from the same kind of ship that is in your docks, it instead deletes the paint from the main ship. (f11 sent as well)
I confirmed the bug and recorded it in the following 35 sec video. It would be much appreciated if @Storm Crow and I could be compensated for the lost paints. Thanks.
