Okay, I understand what the problem is. They basically work, but to teleport you need to be right next to the portal :) I'll fix it.
P.S. By the way, what about the overall map difficulty? Is it too easy?) Because initially I made it too difficult, but after many tests, I had to simplify it...

I don't know about others – but in version 1.4, it seems that the author messed up with the scripts – no events happen at all (neither messages about an upcoming attack in 2 weeks, nor the attacks themselves)...

and versions 1.2 and 1.3 (which, although buggy, worked) have been successfully removed from the forum by the author...
