Trying to get national teams working in Manager Mode.
Alright, I've been doing some research on this issue. Several findings. Some are probably already known but I'm gonna document them anyway so that everything is in one place.
First, it appears that the weird issue where teams would get double booked for friendly matches is still around in '16 I was hoping that they had fixed that since they had an even number of teams this year. No such luck. You can remove this issue by removing the legs for the international friendly matches altogether. Then the teams just won't play friendlies.
I was specifically trying to test adding a concacaf qualification tournament. I've failed. Here's why:
If I just wanted to add another team to the FIFA World Cup Finals tournament, I can do that. But, as soon as I try to alter the way in which that tournament draws teams in, it destroys the entire tournament. By default, there are three teams entered into the tournament via "Get specific team in a specific position." If I try to link these teams through the Gold Glory Cup, try to add another group to the Asian Cup or try to create a new tournament, it fails.
Creating a new international tournament appears to lead to a crash every time. I believe it has something to do with the designation of the tournament as an "InterQual" Competition Type. But, I'm uncertain.
If I modify the Asian cup, I can get the teams playing qualifying matches, but I can't link the results of that tournament to the FIFA World Cup, it breaks the FIFA World Cup Tournament without creating a crash.
If I try to modify the Gold Glory Cup and link teams through it, it breaks the FIFA World Cup Tournament without creating a crash.
So, on this issue, I see no other solution. There is not, in my opinion so far, any way to create a qualification tournament for CONCACAF (or OFC or CAF) and link it to the FIFA World Cup Tournament. I'm pretty disappointed in that result. It seemed like we could find some way to jiggle it to make it work. But, that doesn't seem possible without breaking one of the other tournaments. Even that may not work.
Oh well. If anyone else has any additional thoughts or avenues that may be attempted, let me know.
