Maya - Cant fix faces with zero map area

Dawsky

Hi everyone. 

So i've come across an issue using maya that is pretty weird to me. 
I unwrapped a model manually, and then did a mesh check to see if there is any erros before exporting. 
Non of the cleanup options shows any errors except fot the "Faces with zero map area".
While i know what that means, it turns out the faces in question do have map space, meaning they are indeed unwrapped as you can clearly see from the image. This is not the only face btw, there is tons of faces getting selected when i hit that cleanup button, all of which are unwrapped.
At that point i couldnt care less, tho maya is messing up my uvs in when saving the file, mearning they are all over the place when i reopen the the scene, so there clearly seems to be something wrong with those uvs.
Using maya 2018.2

i couldnt find any info regarding that, so i hope someone can point me in the right direction, as this stops me from working right now. 

Regards
David

Have you tried deleting history and running it again?

check your hypergraph for dead shape nodes etc. if clearing history doesn't work.

Non of the suggeted helped, tho the issue kind of resolved itself after remapping the parts in question. no clue what cause the uvs to go all wild. maybe they were bored. thanks anyway.

I realize this is an old topic, but I stumbled on it while trying to fix my own "Faces with zero map area" error, so I thought I should add what fixed it for me. The faces were cleanly unwrapped, and I tried deleting the history and unused nodes.

Super simple: I just changed the "Area tolerance" in the Cleanup options from 0.000010 to 0.000001. My guess is that those particular faces were just too small to register.
