Re: Moving Istanbul to fix Bosphorus strait bug
It would be brilliant to adjust the campaign map to solve this problem, either by removing the land bridge or moving Istanbul (I can see the downsides of either option). If it's possible to do either, I'd really like to know how.
Modding the behaviour of the Ottoman Empire may help sometimes, but of course the Ottoman Empire doesn't always control the strait. In my latest campaign, the Maratha Confederacy conquered the Ottoman Empire and their end turns took several minutes.
We can edit the treasury of the faction which currently controls the strait (explained by Goreuncle here); even so, a solution which prevents the problem arising would be better.
