Operation system: Windows 11 v22H2
Rom set: mrdo
I downloaded the official binaries on March 30th.
I have not tested on a previous version because I always delete my old versions when the new release comes out. I played this on and off for years on MAME and never encountered this before and all of the sudden it happens 2x in a week.
I just played the Prototype MR Do and I actually got a diamond on my 2nd game on Board 3. No weird completion glitch occurred.
BUT... I noticed when I got the Diamond on romset: mrdo the diamond doesn't appear on the summary screen:

but it DOES appear in the Prototype:
