I have the motorboat, the one shown in the trailer pictures, and I dont seem to be able to add gasoline to it. I stand by it´s side from a pier and I click on the "Add Gasoline" option in it, but my character does nothing.
This is in MP, anti-cheat is disabled, the gastank is functioning and the boat worked. In fact, it worked so well it got me stranded in the middle of the river and I had to swim back when I ran out of gas.

Anyone have any idea what´s going on?
