I can assure you:
We, the frequent players, have been complaining about the faulty kicktimer ever since it was introduced, and that was several years ago.
So it must be veeeery difficult to fix this.
Our demand to let players re-enter with the consent of the other players has not been fullfilled either. So it must be impossibel.
On PlayCatan we already had this option, but Catan Universe has not been able to produce this important feature.
