Bug: Asset image missing after reopening project. Cannot replace image either.

[Saanglao]

Hi,

I was working fine for a couple of days after importing a psd and rigging up with bones, but suddenly reopening my project, some images would be missing. Mesh created over is there but the image is missing.

When trying to "Replace" the image (manually or drag&drop), nothing happens either, any idea if this is known bug and when will this be fixed ?

Config:
Mac/Chrome

Cheers
