Thank you for letting me know! Unfortunately its not something I have been able to replicate on my end with my xbox one controller BUT its hopefully something that will get fixed with the next update which will be exported using a more recent version of RPGM MV and contain a few other small bug fixes and tweaks that have been brought to my attention. Im sorry that its something you had to deal with during your experience with the game.
As for Steam, it is something I had thought about but I am not a fan of the platforms current business practices so I am going to wait on it a bit. Perhaps at a later date. :)
