After turning the GravityBox options back to default, then jus playing games, missing my longpress kill switch, and deciding to turn it back on, it now all works as it should. So sod knows what happened, but for anyone else who gets it, set your long presses to default in GravityBox, restart, make sure Tincore is in the background, and put your long presses back to how they were.
For the record Tincore, your app is amazing. Playing God of Blades how a brawler should be played!!!
By the way, another small question. How do I turn off all the toast notifications?
