With the latest update and the launch of the option to play with Regions, I jumped right in and started up some new colonies to try it out in a local game for myself so I can learn how it all works.
I created a medium and then a small colony yesterday and everything seemed to be running pretty awesome. Except, when I saved the Medium colony and moved to create the Small one, I noticed that several of the larger(early) researches like microchips and civics, had reverted to as if I had never researched them. Which I did, on the medium colony before I created the small one. It was not a big setback though, so I just moved on.
I progressed and got up to mining aluminum and uranium, let them run for a while, and then saved and closed out for the day. I turned it on today and logged in to find that I had absolutely no aluminum and no uranium. Well over half of my aluminum nodes were gone (Harvested yesterday, I watched it happen), and all of my uranium nodes are gone (Also harvested yesterday)

Edit- Research is still resetting after the .72 update. New Zolarg Regions, I get one colony set up and up to crystalline production. I make a second colony because the first ate up its gold resources very quickly, build it up a bit without issue, tech is all researched. I open it up the next day to keep going, and tech is all reset as if I never researched it.
I have the same research reset problem. Every time i leave the game and return, all research under the advanced nuclear physics tech tree are reseted. So i've got a small community college, a large residencial complex, a large medical clinic, a couple of advanced microchip factory and 2 megabot and now i'm unable to replicate those building until i research it back.
