Glad you're enjoying it!
The monolith actions are not blue initially deliberately. The way it currently works, they turn blue once you loop and see that it persists. But it does that for each action, rather than the group of actions, which I admit would make a lot more sense. I'll look into that.
I do agree that the progression of actions doesn't always thematically make sense, but it would also shift the balance of the game a lot if, for example, all actions in an area locked as soon as you started leaving, instead of when you finished. Admittedly, I mostly only made it work that way because that's how it worked in Increlution, but I'm not sure if I want to/should change it at this point. I'll keep a note to consider it moving forwards though.
As for your transient bug being unable to leave, that sounds like an issue someone else had where they had 0 power in the rover, even though they hadn't left yet. I had hoped it was a one-off issue, but clearly it wasn't. I'll take a closer look.
