Jong or Reserve teams such as Jong Ajax, Jong PSV, and Jong Utrecht are in the Keuken Kampioen Divisie at the start of each save, and they are there in real life. In the game however, other Jong teams, such as those that are for teams in the Kuekun Kampioen Divisie, such as Jong de Graafschap cannot get promoted into the 2nd division, even in the main team is promoted into the Eredivisie. In real life, if a team is in the Eredivisie, and their youth team wins the third division, the Dutch Tweede Divisie, then they would be promoted into the Kuekun Kampioen Divisie.
If the main team is demoted from the Eredivise,then the Jong team would be demoted to as they cannot be in the same league, and this does happen in the game, but if the team gets promoted back into the Eredivise, then the Jong team is not able to get back into the Keuken Kampioen Divisie.
This might have something to do with the third league not being playable in the game, but in other league systems in the game B teams can get promoted from non-playable leagues.
Many of the Jong teams in the Netherlands are in what the game calls Dutch Reserve Competitions, there is a Dutch Reserve Competition Eredivisie, and a Dutch Reserve Competition Eerste Divisie. Where the teams are promoted and relegated between the two. In real life, the competition is called the Beloften Eredivisie (https://en.wikipedia.org/wiki/Beloften_Eredivisie) and the Beloften Eerste Divisie. Before the 2012-2013 season, this is how the system worked, where no teams were promoted but after this season, the top 3 Jong teams were given the decision whether they wanted to be promoted into the Erneste Divise, which is called the Keuken Kampioen Divisie in the game. This option is not present in the game however.
"he 2012–13 season also saw a big change to the format: the best 3 teams of that season were allowed to promote to the Eerste Divisie. As a result, the reserve teams of PSV Eindhoven, Ajax and FC Twente left the Beloften Eredivisie and played in the aforementioned Eerste Divisie" (https://en.wikipedia.org/wiki/Beloften_Eredivisie).
It is odd that the option is not in the game as some teams such as Ajax, PSV, and Utrecht already have their Jong teams in the Keuken Kampioen Divisie and thus have a massive advantage as they have something that is attainable in real life, but not in the game, unless you start with it.
There was an old forum post about this that was answered, but the answer only said that if a Eredivisie team is relegated then there B team would be relegated as well, which is not the problem.
Steps To Reproduce:1. Create a new save as an Eredivise team without Jong team in Keuken Kampioen Divisie
2. Have Jong team win the Dutch Reserve Competition Eredivisie
3. Not be presented with option to promote Jong team to Keuken Kampioen Divisie
