I found a very weird bug confirmed on both v2.6.0 and v2.4.1 on linux.
I have a filter:
filter Played
sort_by PlayedTime
reverse_order true
rule PlayedCount not_contains 0
when a game is played exactly 150 times, the next time attract mode is run it doesn't appear in the list anymore, if I edit the .stat file and set the played count to 149 or 151 it is listed again.
