Just had the weirdest thing happen with Nintendont. Playing Star Fox Adventures, loaded a save into Thorntail Hollow very early in the game, and entered Thorntail Store, and this is when things went screwy.

Everything was fine until I was notified as being in the Thorntail Store, and a big gradient color polygon quad appears. I can't exit the way I came, as the game registers an invisible wall if I walk in too far from this point, so I go through the color gradient. I see another, so I go through that, except it's not right in front of me, but is actually a drop off, and I fall to an area underneath all that. I look around, and areas that are shown as open have invisible walls except for one, and that led me to an infinite drop.
I checked the compatibility notes about the game, and it says not to shrink the iso if problems occur after loading a save. The iso I have is not shrunk though (~1.42GB). I tried again, but instead of going straight to the store after loading the save, I took a run towards the Lightfoot Village to the point where it showed the name of it on the screen. Then I went back to Thorntail Hollow and to the store where this problem occurred. This time, no problems.
Notes:
Nintendont 3.382 (Wii U)
Star Fox Adventures (USA) on UStealth ext HDD
Tried both straight from HBC and through USB Loader GX v3.0 r1256 (via channel forwarder)
edit:
Also loaded the save, and fought the 4 enemies that come out near where you pick up the staff, then went back to the store, and it did not glitch.
