Yes I had the exact same problem. Did not find a solution within that AI editor. Ended up making an independent trigger that looks to see if a certain building is dead the instructs an SCV to go build one if it doesn't find, say, a barracks in the place it's supposed to be. A little bit of a roundabout but only takes about 15 min to make a whole base autonomous if you make an action definition.
Yes, i made sure that AI has 500k starting resources & some resources in base and all requirements. I tried to play around with those triggers, sometimes ai kept rebuilding it indefinitely, sometimes not at all. I will try experimenting with it a bit more, but for now i just go with no rebuilds. I originally planned to make AI rebuild in higher difficulty levels of map, but if it's something that players don't really like, maybe it's better to design future maps without AI rebuilds - will try to go with it, thanks!
That sounds like good workaround. For me (=editor newbie) it sounds quite complex to do, but i will try to look into that. Thanks!
No prob. Here is how it looks if this helps. Every 30 or 60 seconds or so on a periodic timer I have this run. Basically it checks to see if there is a building in a small rectangular region (where it should be) and if destroyed, grabs a worker and tells it to build. That's the blue rectangle.
The following part creates a tech reactor as an add-on if the building needs one.
