A couple of bugs you might not be aware of...
The first one is probably due to the MtF path being basically pasted on top of the bimboization path. When starting as a male contestant if you have them purchase the swim trunks and wear only that and shades to go swimming, even when no breasts yet, you are treated as if you were running around nude by the game's code. This results in temporary humiliation mood debuffs and if you encounter other contestants it results in a "Spotted by contestant nude" debuff. Not sure if this is caused by the trunks not covering the chest, or if it caused by the shades not being connected to the trunks and so it misses the trunks.
As probably a side issue to the first bug, the male (who supposedly wants nothing to do with being transformed) can wear the female swimwear as his only clothes worn without problems despite that being vastly more feminine than other non-swimwear choices that he has issues with wearing.
Pursuant to the side bug above, at the very start of the game if you have the male version contestant wear nothing but the sex appeal swimwear everywhere from the beginning, avoid masturbating, take from first week the popularity while streaming penalty and do only tasks that give lots of popularity and mood gains, you actually can end up having more votes than Erica does for the second week, but she still gets the round win while it labels you as a miraculous change up in votes and puts you in second but includes your vote count and hers which shows you should have made first. Anyway as a result of this forced week loss you take the second penalty.
The hanko quest seems once in a while to be a bit buggy. I once completed the quest by giving it to her, and the very next day she was crying about it being lost all over again which forced me to repeat the quest. Usually however that doesn't happen and it just finishes normally. Not sure what caused this as I have been unable to personally replicate this.
Purchasing a bunch of injectors at once seems to break your game code for some reason. Despite having 4 injectors, once you use one of them on another contestant sometimes the game thinks you don't have any to use despite still having several left.
If you accidentally buy 2 maps and only buy 1 day planner it occasionally acts a bit buggy trying to use the planner. Sometimes it works fine, other times it causes a fault or leaves you getting random issues.
Speaking of the planner, if you set a timeslot to have your contestant move somewhere but not take any actions it instead stops at the previous timeslot.
The blond and redhead are coded to "revenge" tf you after you tf them, but this code triggers even after they are 3/3 and supposedly unable to take any actions. I haven't tested it yet but this makes me wonder if the Japanese girl Himako also will forced modify him into becoming her replacement even after she too has been disqualified already.
