I found the fuel tank for the truck but now it has disappeared. Is this a glitch and how do I get it..

Same thing with me. Plus I can’t upgrade material storage since you need 337 bricks but you cap out at 300. This game is very glitchy. It’s also annoying that you have to have the game open to progress….

I picked the fuel tank up, but it has disappeared it was right in front of the truck. Now can’t move forward. Game needs to be sorted.

I have 650 fuel and it only needs 500 and now I’m stuck

You don’t need to upgrade. I looked everywhere for the truck battery and then started upgrading the medical center and everything I could. Then I scrolled right from the main camp, across the stream over the lily pads, the first house there had a truck battery. Not sure if I missed it before or I had to upgrade stuff to have it appear. Game ended abruptly after I collected it. Not prologue, just “the game is over”…

Thanks. Same happened to me. It jumped me back to level one. Frustrating, thought there would be more levels.
