after update 0.2.0 you can no longer map one button to have 2 different functions.

Example: X button is used to pick up/interact and I used to also have it assigned to swim down. Now when I try to map X button to swim down the game tells me X is being use for INTERACT and asks if I want to change it to the new function. I also used to have A button mapped to swim up as it's secondary function. Same issue.

Another example: If you set button mapping to default the A button is assigned to both jump and glide. If however you deselect the A button from let's say glide and then try to reselect it for glide the game will again tell you that the A button is assigned to jump and asks if you want to change it's function...

Secondary button mapping slot has no effect. If you try to use the secondary button mapping slot game tells you the button is already in use and asks if you want to change it to the new function.

P.S. I absolutely love this game. It's so much fun and has so much more potential. Well done to everyone who is working on Grounded. BIG thumbs up

 

that's odd,  i also have X mapped to interact and swim down and it works just fine.  guessing it's your save file and the new update glitching together.  Try a new game and see if it works.
