Hi Roman,
I'm noticing a strange behaviuor since some time:
1) This is a picture of my present situation: I'm using clrmame 3.122c and pointing it to a freshly compiled mame0.129u5.
After a "new scan" with all fixes activated I'm missing 20 sets and 70 roms

2) I do a rebuilt with following result:
created files 57

3) I do a "scan" and get the following:
missing sets 20 (as it was at the biginning, like if nothing was rebuilt)
missing roms 12 (which of course is the correct number of what I'm really missing, but it computes bad from 70-57=13 !!)

4) I do a second "scan" and finally get the correct count both for sets and roms

Is it normal that I have to perform 2 consecutive "scan" to get the right numbers in the statistical window?

ciao
