Adding this here cause it gets more attention and someone may have a solution to it:
I tried to update my mount macro for my paladin recently to a new mount to use, it has the corridor creeper in it so I don’t have to bind both. Any who I wanted to bind the great sunwalker kodo to it, and it doesn’t work. I’ve spell checked it, put in different mounts into the macro, and nothing seems to work with it. So it seems to be specific to both of the paladin specific mounts, as the sunwalker kodo also doesn’t work.
I imagine this will be never properly fixed, as its a multi dollar company, yet kind of find it amusing in a way such a simple and stupid bug exists honestly.
the macro will always read the first one and cast the first one first, if you hit it in succession again it will mount you on the creeper. Along with it cancels the first cast in the maw automatically and casts the creeper instead, won’t be using it for much longer given 9.1 and all its stupidity that its bringing along with it.
