So let me get this straight.
You don't like some outcome = must be a bug that needs to be fixed.
I doubt it was 4.5, more like 4 ish max...
3 is pretty generous tbh considering you ended tournament in 3rd round against 1st non bot
You're sitting in the middle of table with 7-4 record.
From last season you have around 3 stars from last season.
Since you don't have very recent purchase I doubt you'll have Manager score on 5 stars too.
Since the tv game was also your last game I guess you don't have that score too high either.
Was all the options you have to win that match exhausted? Absolutely not. GDP is empty.
Also those ratings don't mean much anyway unless you have boycott
