To the right of 3-4/3-5, instead of being the 1up game the Spade leads to a bro fight with no bros, forcing me to lose a life by time up.

my best guess is since that tile was originally a bro fight tile, that space is more or less just to prevent a hb from moving there. id suggest not entering any spade game on its modified spaces. im pretty sure this will happen for all the extra spade games in worlds 2-6. i could be wrong.

Yeah, this appears to be the only spade tile I forgot to update when placing it. All the other ones should work normally. Thanks for reporting!
