No it is not true. When you clcik it causes a slight lag i guess you couls say so when the builting is constructing the number freezes then jumps ahead making the illusion to test have to things build aat the same time and clcik on fast.
It doesnt save any time. I have timed it i have run tests it does shit. Its actualy bad for your becuase in all that clciking your doing you could be doing other things like order units of upgrades.
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
