Hey there, Lone_Wanderer here,
Are playing the public or the patron build?
This bug has been fixed by now. The reason why the Brando content only looped sometimes is, this bug only occured if you had slept with Brando, which skipped part of the next day forward.
This had also skipped some game logic, so the game still thought it was on day 3, even though it was already showing parts of day 4.
Cedrik does have two dates at the moment. In the first one the two of you hang around in the spa area, in the second one you go to a diner together. Have you not been able to access the second date?
And regarding your question about art commissions: We are fine with fanart, as long as it isn't being resold. So, commissions are fine, but not if you were for example to wanting to use this art in selling prints or within another game that you make yourself and then sell.
Commissioning fanart is fine by us. You can probably even ask our artists directly if you would like them to make you something.
