A button on controller summoning horse

Currently the A button on my controller is having me mount horse instead of talking to people. I haven’t remapped the keybindings at all and it has been happening since the last patch.

Edit: After some more testing it seems that multiple commands are mixed up seemingly randomly, Y will open the character screen mid fight, A is also now moving cursor in random directions, sometimes button presses are just unresponsive and lead to and input at all.

I have tested the controller on a few other applications with no issue and had no problems before the latest patch.
