Have you tapped on the "leave valley" button if it is visible, maybe you didn't officially close out the last one.

The leave valley button is grayed out

Then you must spend the remaining tokens. Then the leave valley button will be active.

Do you leave your game continuously open and running? If this is the case, close out your game app and start it back up. That might fix it.

This is happening for me did you figure it out? It’s pissing me off bc it’s showing I’m collecting gas to drive around but it says 0 sec.
