Okay, so I have this problem. In my games, sometimes a navy will get stuck in a little inland lake, like this one in Veneto province or the one in Nicaea for another example I've seen this happen at.
Does anyone have any idea what causes this and if I can fix it?
Besides being a permanent eyesore (even if the faction is destroyed it'll be a rebel fleet!) it must be taking up resources from Venice and possibly even causing CTD or bugs. I could imagine this being a problem if another unit gets sent to the same lake by the same process, and the two are stuck on the same tile with nowhere to move to... would a ship attempting to force itself on a land tile cause a CTD for instance? Who knows...
