Hopefully fixed for the next release. The Phoenix's Rec Room did not have any move minutes defined, so it used the default room's time (5 minutes)--it should now be set to 1 minute like the other rooms.
Some rooms are interpreted as larger areas than others, so they have a higher move minute count (such as interior vs exterior areas). How the movement time passage currently works is it will only take the move minute value of the current room and apply that to the travel time. I've updated so it will compare the current room with the destination room and use whichever move minute value is higher. This should hopefully give a more consistent and expected result for the time passage between rooms with differing move minute values.
