Did the AI get way dumber in 1.13?

[Wizzington]

I'd really like some concrete examples / bug reports of AI misbehaving with forts instead of 'AI doesn't understand forts at all', because I'm really not seeing the latter in my own games.

One problem i have seen is that the IA with a 40k army, siege a non important fort with lets say 20k stack, and have the other 20k stack waiting in the nearest province.
Meanwhile, his allies are fighting and losing every battle in another places.

It seems like the IA, sometimes, give excesive priority to estrategic "useless" (At that moment in the war) forts instead of helping allies fighting battles.

The counterpoint to this is that when the AI runs off to help in every battle, it becomes very easy to trick it to leave sieges, and results in it failing to capture wargoals and losing the overall war.

The main problem I have with the AI is how they always give up very important sieges and immediately start sieging again. Now I hire a few mercenary units to make sure the progress is not lost on my allies' sieges.

Pease submit a bug report with a repro case.

Really? Movement around forts is all kinds of broken, not just for the AI, but for the player as well. As soon as there are multiple forts adjacent to each other and/or adjacent to country borders, the zones of control go crazy. Here's what happened when I tried to move one province over to Avignon, with Forts in Avignon and Provence. This is just one example of many.

That has nothing to do with the AI (and is not at all the result of one click on Avignon, but very obviously multiple clicks).

Yes, it was one single click on Avignon. And as I said, movement around forts is not just a problem for the AI, but for the player as well.

Unless the pathfinding is fundamentally broken, that is not possible as it would not continue past the province you clicked on. I will set up a test case just to be sure but I find the pathfinding being fundamentally broken to that degree without anyone else catching it to be very unlikely.

EDIT: Set up an identical scenario and clicking on Avignon goes straight to Avignon, while clicking on Provence and THEN shift-clicking Avignon gives the precise path you have. If you provide a save, I'll test with it too but I think you just misclicked.

 

[Wizzington]

As I said, I just set up an identical scenario to yours and the only way to get your crazy path was to click Provence and then shift-click Avignon, so unless you can provide a repro save I'm going to have to assume you misclicked. The second screenshot you posted is entirely different.
