Attached are my cliff error finds for the main overworld so far. Not sure if you want to count the first one as an error, but it's definitely an inconsistency. The ones in Deadwood are southern cliff tiles that are proportioned incorrectly.
I will never include the cliff by Fuitad's (old name for place north of The Joint, west of the bridge) because its tile errors pretty much need to be taken as sacred.
Edit: Balamb Island has the same cliff tile errors as Deadwood that I posted examples of. Air Asia Town was also full of them when that was around. Don't know about the VIP Island because I don't have VIP.
Also, my previous cliff tile error statement was primarily because the visual cues I used were for older cliff tiles.
