Why does this happen? I made a transparency map to make the jeans into cutoffs.  It worked fine a few weeks ago.  Now when I load it: 1. Nothing happens 2. Nothing happens to the bodypart selected and the rest of the jeans are still partially visible. or... 3. A second later, the transparency map gets replaced with the texture map.

All the nodes are connected correctly, and I deleted unattached ones.

Thanks in advance for any help.
