Losing the master password is fatal, as everyone will be using the same tier of authorization for base management.
I'm not sure if admins can and will assist in a master pw reset, and probably will only act upon a very comprehensive and complete player request. Got to justify why it has been lost in the first place, and why should a new one he given to someone who's not the founder or main owner.
i have a admin pw and when i use it ti list pw's only viewshop and admin ones are listed not the master pw. a pal who used to play built the base while i was there and we shared running the base together.
