The production team works across all shows (and likely cross brands as well since Nerdist got folded into G&S), so they don't get a ton of time to workout the kinks of the setups ahead of time since they're constantly shifting from one show to the next, all of them using unique setups and different staff members.
This is old but
here's a timelapse of what they have to go through in just setting up. Keep in mind as well that they have several other sets as well for the other shows so they shift focus from multiple sets on certain days.
Absolutely Critical Role is the flagship and it does get more attention than other shows (Ivan had to use his own money for the specialized gaming table they use for Game the Game), but also consider that some of the other shows Welcome to the Wednesday Club, Talks Machina (different set), Tabletop, Signal Boost, and Ashes of Valkana all also star and/or are produced by members of Critical Role as well. The money has to be spread around and projects balanced.
