[BUG] F9 Cache to disk per node is broken.

When open Cache to disk dialog and press prerender - it starts rendering, creates a folder, but renders nothing in the end.
Else is this: if none viewer is selected to look through, it renders like instantaneously, and that's because it doesn't really render anything.

Which build are you using? 9.0.1 build 3 caches fine for me on Windows 10 Pro.

Right, I had the same version. Reinstalled it and it worked. Also I'm experiencing some strange behaviour with mask nodes - when I try to look through them they freeze all viewing and show nothing, but if l connect them anywhere to the mask input an look through, everything is working, also similar behaviour was with hcv tool, that becomes red instantly and refused to show any effect. In both cases, the removing all app data folders resolved the issues, but by doing this, I lose all bins I've created and have to recreate and reload everything from scratch. do you know where to look for something that causes the issue? At least not to kill each folder, but some of them?...(In the first place I tried to remove the preferences but it didn't help.)

And what the stamps are? They took up almost two gigs in mine case!
