So I’m curious. I may have missed some update but I just logged in and ran to check two of my 1x2 portals. They are almost next to eachother. I knew the fuel had ran out and they were to close when I looked into them like usual. BUT they didn’t shut. They both had 0 seconds left. I waited 30 seconds and they both stayed open. So my question is if this is intentional now it’s a great idea! If the portal is simply not used it will remain open to negate a reopening cost. If I was just glitched (wouldn’t surprise me with the stuff and portals with me ) I think it should be a thing :).
And yes I was about to leave the room and grab my fuel to put it in. :).
