i searched the net and found two answers:
the game support says "If you are upgrading any of your units, and then decide to upgrade the Laboratory, the unit upgrade will pause while the Laboratory is being upgraded. The troop upgrade will pick up where it left off once the Laboratory upgrade has finished."
while the wikia says: If you decide to upgrade your Laboratory while there's a research going on, it will not halt the research progression and will continue regardless. However the research progress bar will not be visible during the upgrade of the building because It is replaced by the building upgrade's progress bar.
which one is true? other people say that the research will be pause while upgrading, and other say that research will continue even the lab is upgrading..
thanks a lot!
