VCS project and Colors

I have a large project that I manage in the Xojo XML project format.
The other day for a test, I saved it in the VCS project format.
But when I attempted to RUN that copy, a number (not all) of the colors were wrong (as in either BLACK or WHITE instead of blue or brown as an example)
Returning to the XML version, everything was correct.
No code changes occurred between saving it VCS and running it… everything else about the VCS version seemed to be “ok”

What version of Xojo are you using?

2016r4.1 under macOS 10.11.6

I see those color changes sometimes after a Xojo IDE crash, when i load the Recovery Project. Happened also with 2017r1.
