Attempts to load map via trigger kicks me out to the campaign screen

[WarCortez]

I'm trying to make map crossing work. I could cross to a submap but when attempting to go back, the game just exits to the campaign screen. That happened before when I had wrong extension given but I don't think it's the case now. After hours of trying to make this work, I just don't have the focus and the idea what went wrong.

Edit: I did a testing on a working transition example map I downloaded. I rewrote the save/load names and they produced the same issue as my map. However, when I manually typed back the original names, the issue still remained.
