I tried asking this in Tech support, since I don't think it's a bug, per se, but I've gotten no reply, so I am trying here.

So I play on PS4 with a controller, and I've noticed a bit of an issue within the past few days. Basically, on a controller X acts as a mouse click, with another button acting as a right click, for me triangle. Well I usually am able to select an item from my inventory with X, then I could hit X again to bring up the sub menu, the menu I'd get if I pressed triangle initially. But lately it hasn't worked like that, and has only been giving me the option to move the item in question. This happened one morning, but somehow fixed itself later that night, but started up again the following day. I'm curious what happened as I haven't touched my settings in forever. I will say I noticed yesterday that I was able to use the triangle button to bring up the sub menu then use the item, but why would the functions switch. And X still functions as my mouse click. Anyone have any thoughts on what might of happened. It's not game breaking, but it is frustrating.
