Unfortunately, I've stumbled upon one. Fortunately, it's for a side quest, so I'm assuming the glitch won't break the game in terms of impeding my ability to beat the game.

There's a side mission where killing three Glinthawks is necessary to progress the story. One of the three Glinthawks always gets stuck in a mountainside and as result, I can't kill it despite the fact I am able to get it's health down to zero. I've reset the area about three to four times and still get the same glitch.

Hopefully this will get patched up soon.

This isn't a glitch persay, but the platform jumping also leaves a lot to be desired. It feels very finicky when having to traverse heights in the game. I don't know if that's something that can get patched, but I suppose time will tell.
