At this time it is risky to build up more than one research facility.
If you've got more than one research facility you should never change settings of any facility while researching is in progress.
If you change settings during research all running reseach projects will be resettet and beginning from scratch.
This bug may only show up by changing settings of research facility 2 or 3.
Facility 1 is not affacted by this bug.
So, if you are using more than one facility have in mind that you might be vulnerable for this bug.
