There have been some issues left and right with controllers and buttons not working or doing more than one thing at a time.
Problem is that the same controller and OS combination works for some players, where it doesn't work for others.. which makes it very hard to find the problem. IF you have issues let me know which controller you have, which OS and IF you are using any controller mapping tools or settings that might change the behavior in some way.
The changes in this version might mean you have to remap the gamepad settings, or do a "Reset to default" and then change them to your liking.
I removed some code that hard-assigned buttons to the interface portions of the game, which probably caused more troubles than they fixed (compared to my other games where these issues were happening much less). So I reverted all that code back to the normal state of my games, and I hope that fixes some issues for people that had buttons trigger multiple actions.
Also check the gamepad dead-zone setting in the menu, because that might help with left+right movement issues (if you're gamepad has seen some battle time in games over the years, those sticks can get really funky with triggering responses).
I don't think it fixes all the problems, but do let me know if it did fix a bunch of them, and then let me know what issues still remain!
