I have an issue where Dashing just kind of stops working at random times. I'll be fighting Slime King with Phoenix Mark thinking I can dash right through him when he's about to close in on me. Nope. I just walk straight into him because the dash wouldn't register. It'll happen randomly as I'm exploring, too. I like to use the dash to speed boost me, but it'll just stop working for a good 3 seconds. I get there's a delay between each dash, but this is on a whole other level.
