Both literally and figuratively.

So, I had my controller set up via Steam for Switch controls. For some reason the other night, Valheim seemed to "reset" (maybe there was an update?) and it reset to Xbox 360 controls. Despite going back into Steam's settings and remapping things again, it doesn't seem to be working. I'm trying to adapt to the new control layout (new to me, anyway) but it's not going well. I already went into Big Picture Mode to change the button functions. Didn't do anything. Any ideas how to fix?
