I've noticed a few annoyances here and there, never a collision issue.
For me, these were annoying:
- One shrine has boulders rolling down a hill, once under control, I could push around them with link. but if I touched them,after I pushed them, even from the backside or side, I'd get damaged. kind of annoying.
- When trying to mount the zora boss, I don't know if it's intentional or not but when I had to shoot arrows at those for areas, my ride kept forcing me to the wrong side for the last of the 4. Maybe it was intentional, so that I was forced to be more challenging, but I thought it was a bug at first as I shot out two in one leap on the first side, I restarted from a save, and did it one at a time to find the same behavior. Maybe not a bug, but this scripted sequence seemed less polished than the rest of the game.
ahh well...
