I also noticed that it doesn’t care about the 15 seconds at mgpDoubleUntil(15, 4) and instead uses the 4 and plays 4 times before cashing out.
I have also noticed this as well, and from reading the scenario functions notes, it seems like miqo thinks that this she’s playing the Finer Miner, since she’s taking both the Finer Miner difficulty and “double until”. It also explains why Miqo feels like she’s making more mistakes as well. I think I’ll play at the Gold Saucer for now and wait until there’s more official support for housing related minigames
