I just ran into a nasty set of bugs in a somewhat unusual situation. Unfortunately, I didn't even know it had happened until months afterwards, so I have no savefile, but I will describe as much as I know:

France (human) at war with GB (AI). France controls Denmark. At some point, I went to check the status of that fleet, which had been blockaded at Copenhagen, and found there only a GB blockading fleet (blockading an empty port). Looking around, I found the Danish fleet (somewhat reduced) in another port.

Reviewing the log, this seems to be what happened:

Some months previously, Russia (AI) had been at war with France, and it was the Russian fleet blockading Copenhagen. Russia surrenders to France, and so the blockading fleet became a "friendly" fleet inside the port, stacked together with the French.

GB, seeing the fleet now unblockaded, moved in its own blockading fleet (good AI move there, at least).

Three months later, Russian temp access to France ends. This is when the chaos ensues.

What should happen: Russian fleet leaves Copenhagen, sails past friendly GB fleet (Russia and GB are allies).

What did happen, per log:

First, Russian fleet fought a battle with the blockading GB fleet (BUG 1). Russians lose, retire into port.

Then, French-controlled Danish fleet tries to evacuate (BUG 2), fights GB fleet. Danes lose, but nevertheless are allowed to pass the blockade and escape to another port (BUG 3).

Then, Russian fleet (same month) tries to evacuate repeatedly, fighting the GB fleet each time, until there are no Russian ships left (BUG 1 BUG 1 BUG 1 BUG 1....)

The result was the picture as it looked when I came along to inspect Copenhagen a while later.

By the way, this is clearly similar to Mantis bug 565, listed as fixed for 1.08, but the situation here was a little different. In that case, there was only a French-controlled minor fleet and a blockading GB fleet, and the fleet evacuated (properly) when the city fell to a third party (Russian troops), and fought a battle (properly); the bug there came when the fleet tried to evacuate repeatedly instead of being scuttled.

But in this new case, the initially evacuating fleet shouldn't have to fight at all, and the French-controlled fleet shouldn't have to evacuate (and if it does it shouldn't succeed if it loses the battle). So I don't know whether the fix would cover this situation.

If you see a chance to get a save where I can dupe this then let me know if you can?

I was able to dupe it pretty easily using all human players, and posted it at Mantis.

The only difference I see between the dupe and the original is that for some reason in the original, the Russians fought first, then the Danes, then the Russians again and again; in the dupe, the Danes go first, then the Russians again and again. Otherwise it's the same.

Also, occasionally the Russian fleet will beat the Brits and break out, which prevents seeing the bug in its full glory (though you still see three of the four parts). But if they lose the first combat they'll generally keep losing till they're all sunk.

The repetition of the combat is the same as Mantis 565, but the other three parts (Russians fighting at all, since they're not war; Danes evacuating when they control the port; Danes breaking blockade after losing combat) are new, I think.
