I have created, actually expanded Polish Hockey League up to 30 teams. I have used the settings from the NHL with 2 conferences and 4 divisions. Have also used exactly the same stage settings as the NHL has.
But, when first time have started the game it said something like this:

And after copying NHL schedule from Schedule Template I had this error:

So, after this error I have gone through some Team ID checks from the template and real team ID's from the editor and realized that in-game team ID's are very different than the ones used in schedule template.
Real ID's


Schedule Template ID's

Can anyone help me to find out where these ID's came from?
Without knowing these I can't get correct schedule dates set up in my db.
And I don't really know how and where to find it or what kind of tool use to generate fixtures using my PHL teams.
Al help greatly appreciated.
