Why does the AC temple disappear?
I noticed it was gone because I didn't see liftic moving around anymore. The liftic pod still had 494 liftic when I noticed. Then obviously the AC would've slowly been eaten by the creeper but I had already capped off all the emitters.
The temple only takes a certain amount of Liftic before going away. It is to ensure you can't softlock the mission by spending all your Liftic on the temple and having none left for the totems. A surplus is left because you can lose liftic in transit.
