Yes, I have bound the action menu to the key "P" before the patch and it worked fine. After the patch and the same key config I only get the players screen when pressing P, not the action menu although this key is only aligned to the action menu within the config.
Another problem I'm having: I have now bound the action menu to "Tab", but I can't open the action menu when the map is open which is very annoying since I want to order support to a certain point on the map and I always have to open the action menu BEFORE entering the map, otherwise it won't work.
Feedback from someone who has the same problem fixed or from the developers would be very welcome.
