Not a bug as such, but thought I'd throw it in while I'm here. Don't recall seeing in the list of bugs, apologise if already being considered.
Heritage and preseason guernseys are identical for most clubs. In other words, the heritage guernsey also shows up under preseason guernsey for clubs except Richmond, port adelaide, and St Kilda (AFAIK). In these cases it should be removed as it is inaccurate. Some clubs such as Essendon typically don't wear a different guernsey during pre-season. For many clubs, preseason could be replaced by another commemorative guernsey such as Anzac, multicultural, and/or indigenous round geurnseys. This would also add to the immersion during season/career mode if teams wear the particular guernsey for corresponding rounds/games.
Not a priority, but would love to see.
