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.

I am running the desktop version
Mac high sierra 10.13.6 OS
MyColony Version 0.72.0
