So reached the new End of Content marker (EoC) after 29 loops. Probably 15 of them were caused by failing to reach a destination and running out of food or water, but that taught me that the path wasn't optimal. Way too many branching paths and I get confused on how to keep all the information straight.
Will do one more loop, to visit Santorini, and see if I can prevent the boom there, now that I have remote tram access.
I'll think up some suggestions (outside of current feedback) probably for tomorrow.
EDIT
Just noticed this. You can't unblock or boost tram power from Central. Only at quarry.
Boost Tram Power doesn't share commonality with the action if performed at Astrape. Same with Unblock Tram.
EDIT2
Increasing speed of tram by +50%, only applies to Astrape trip. Doesn't speed up tram rides between Santorini locations.
EDIT3
Most things react to the removal of the artifact at Astrape, except for the Water Filter machine. Both its description and the message log is the same.
EDIT4
Drive towards Dam, from Astrape (when santorini explodes, so you can't travel back to it), doesn't share commonality with any actions, and is set to 5 minutes.
