1) Yep, that's on the list to sort at some point. Some minor locations (like the dam and Strabo's buildings) already have them. The issue is the actions for the tunnel and lost rover aren't in their areas. You never leave the rover there, and the actions are actually inside the rover. So it'll take a bit of work to shuffle those around, but I will sort it.
2) Yeah, I've tried playing around with the wording of that in different places. I think some places say it better than others now, so I may have to check for ones which are less obvious and update them.
Glad you're enjoying the update!
