Hi Guys,
I think there is a mistake in the sailing system with rafts (maybe also with other ships). I accidentally bumped against a shipyard with the front of my raft and got stuck between two pillars. The wind was perfect for sailing backwards, but it did not work. The raft was still trying to sail forward, although it would have had to sail backwards (which would have been helpful in this case).
I've attached a picture of this problem.
