"King of the Hill"

The following situation occurred: We were playing 8mm6a. I was red. After almost a month of playing, it turned out that I simply have no way to reach zone 19 (the one that leads to the center). There are two two-way portals of different colors leading there (one on my base, the other at the brown player's base), but neither of them works. And I didn't find any pairs for them on the map (maybe I didn't look carefully enough). I built all sorts of towers – there are no DD or fly units, nor in the scrolls. As a result, I was completely isolated from the outside world, despite having good stats and an army. Amilu doesn't mind replaying, or going to a best-of-3 if time allows, or finishing this game. The decision is up to the organizer. Saves are attached.
