Ok, thats weird. If you do a simply right click on a machine, nothing happens at all? Do you have something in hand while doing that? Also, at the absolute start you can't pick up anything, so you can't accidentaly delete the coins. It should work after the first two researches.
Sorry, I restarted based on your suggestion about right-click being enabled after the second research, that does work.
I'm playing on Firefox. Normal mouse. Connections and resources still worked. Maybe the flag wasn't set from the older save, since machines were moved with left click in the previous version?
