Continuing the discussion from Grizzly rage abilities missing (detailed info + steps by steps to reproduce):
This is actually happening on xbox for me, when i switched my B & Y button in controls because i like Y to be my core skill & x my basic, (doesnt matter when you can reassign anyskill after you unlock all the buttons but i still rearrange them a little in the controls, so it only matters really for when im starting a new charactwr and have to use B for core skill for a little bit. Anyhow Trample seems to disapear when i do that, ill try doing it again & see if it does it still. OK just did switched it again & it didn’t seem to glitch this time.
