I started playing the oversrive game mode at the beginning of this season in bronze tier 3. I gained fans for wins and was promoted to higher tiers until I reached hall of fame tier when I reached 182k fans. Up until this point there were no problems.
I then had a losing streak of about 10 games and after losing about 2 or 3 games I should have been demoted to elite tier 1 based on the number of fans I had left. This did not happen, I was never demoted and stayed in hall of fame tier and I lost 11k fans for all of the 10 games in my losing streak. This meant I went from hall of fame with 182k fans to hall of fame with 72k fans in 10 games.
At this stage I still gain13k fans for every win and 11k fans for every game I lose and I am still in hall of fame tier eventhough I only have 60k fans and should be in a lower tier, i.e. elite 3 for example.
The problem is that I am not being demoted to lower tiers where the fans gained for a win is much more compared to the fans lost for a lose.
