So is ZIT training on-site still unstable?

Updates section hasn't said the problems with training it were addressed, and there's still some funky stuff with Illustrious (autolabel worse than usual, had to try multiple times to upload archive, though what I've trained since has worked), but I've seen some labeled as made on site in the newest. Wanted to know if it was worth trying again or if I was just going to get one broken epoch and lose buzz if I tried again.

Pic unrelated. Random old gen.
