That's where the bug was! I was wondering why the green unit was acting strangely and not using the portals! The main thing is that the path to the tent is visible in the editor, but it's impossible to enter it from above. Thanks for noticing, I've fixed it. Many objects are made inaccessible on purpose, and some have only a supporting role and will not be discovered during the walkthrough. But if something raises doubts, please let me know. I ran the map through a check, found about ten unintended inaccessible locations, moved some, and others gave me a new idea for use. I redrew one of the underground locations and a bonus location. It even looks better now. So, here it is. Version 1.1.1.
