I found a 'problem' and i'm not sure if it's a bug.
AI does not trad back, i mean the AI is set trades but the caravans or rafts not travel to take the resources.
Can also happen when the trade building is get abandoned or deconstructed.

I saw this a few times lately, as well the game is LAGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGY. i can't play it, only 1/2 FPS, but i'm sure you going to improve the performance on the game.
The crashes happen mostly (as i remember) when deconstructing/upgrading a building(s) with negative amount of idlers.
