Ground set wrong

Went to grab some loot off the path after the Rotating Bridge, and my character jumped under the floor there for a bit. Could still move to the loot and back, but the character was visibly inside the path for part of the way. The square to the left of where I stand was on the right height (the character had to jump down from that to be where he is, and climb up to get out), but the one he stands on and the ones right of that until the big climb were underground as can be seen on the picture.
