For a while, if I was in 3rd person sailing, if I pressed a left or right arrow key then the view shifted to another ship. I've no idea why this started happening. It kept happening if I reloaded a saved game. It kept happening after the game started crashing and I copied everything back from backup directories. If I wanted to use a command and didn't want the view to shift then I had to be in 1st person view. And then, equally without explanation, it stopped happening and I could press the arrow keys as much as I liked, the view remained stuck on my ship as it should.
Could someone confirm this and maybe post a compile or error log after it happens or a savegame after it happened?
