OK, I know I am using the right version of my quest this time. In a mini-level in my quest built in 2.10, I cannot open a boss door on the north wall after having a guy in the room. The room is set up to give 20 rupees and has a message string. After collecting the rupees the guy goes away as normal but the door won't open. This has not happened before in 2.10. The boss key does show up in the subscreen and I have already successfully used the key on a door in this level. I am wondering if this bug also occurs with regular key doors as well.
Boss door on north wall in guy room won't open - build 346
The locked door code was buggy: it checked if the next screen lay in the bounds of the current map, or if there's a Scrolling Warp in that direction, and finding neither, panicked.
Fixed in the next build.
Confirmed that this is fixed in build 357.
