Overlay and base textures refuse to save

[TheMurderousCricket 5,045]

Hi All,

For some reason, when I try to edit a lot's base or overlay texture, the texture is never applied.

When I select a new texture, and click "ok" the texture loads to the preview. However, when I switch tabs (say, to "props") the texture just disappears. Neither does it save.

It happens during editing of all possible lots. I checked several of them, vanilla, custom, NAM pieces, you name it. And it's just the same everywhere.

What's the problem here?
