Well, there goes my 2nd campaign

I have only had CTD problems with stacks that contain ships of the line. And only after researching the techs that speed them up, copper bottoms and topgallants and so forth seem to exacerbate the problem. Once you've got some first-rates or third-rates with copper bottoms, be very cautious about clicking on them, especially in the Mediterranean or the Americas.

Yes, the ship CTD has something to do with the range calculation (green area) of Ships of the Line. Since the range shown is always the range of the ship with the leastmovement points left, merging a ship (which then has already lost some of its points) solves the problem.
It occurs almost every time around Newfoundland (I don't send SotLs there directly from Europe anymore) and rarely elsewhere (once or twice somewhere off France for me), which leads me to suspect it has something to do with a specific coastline feature up there.

Findind out which corner of the cursed island that is should be easy. Simple trial and error of moving a 2nd rate or something closer and checking which is the closest you can get from each direction. This would be terribly time consuming though, because of the multiple game restarts, so I'm not going to do it. Any students with too much time around?


Edit: On second thought it can't be the range calculation for the ship stack or the we would see CTDs when the AI moves ships from that area. Could it be the green range circle? Anyway to disable this?
