Hello... this is what I have done:
1) Fixed by hand the alignments on a big file (a merged file with about 2K faces)
2) Rebuilt the masks (extended)
3) launched the training: No way! it says aligments with no faces.
4) Run the remove face tool TWICE: (the first time it did not fix anything apparently)
5) The second time it apparently removed a few faces..
6) Started the training again.... I have lost the alignmnents of ALL the faces i manually edited.
....
I have enough backups to restart... but... this is kind of weird....
What should have I done instead?
Thanks!
