It happens more often than I would expect. Some renders are almost complete pretty fast, except for one or two frames (priority mode). And then it seems like it's stuck at 98% or 99%.
I'm having this situation again (stuck since 24h) and I wonder why it's not possible to just pay and download the frames that rendered? Then launch a render of the 1 frame missing. Instead, I feel like my only option is to re-render everything. Is there something I'm missing?
EDIT: Yes, I was missing the fact that I can cancel the render and download the frames that reached 100%. However, I hope my "reputation score" won't get too low by doing that!
