Major Issue in Floor Generation

[SourKiwi]

Copy/Pasted (roughly) from Steam forums:

I just ran into a major issue on my current run. I'm stuck behind a locked door, with no keycards in my inventory or anywhere on the map, and the boss is somewhere beyond that room as I have explored every other possible location - for both alternate paths and/or key cards.

I have no idea if I'm missing something, but I've explored every nook and cranny of this map. I just bought the game today, and I'm loving it, but this seems like a huge oversight as I literally cannot progress through the game and now have to abandon this run. And with this in the back of my mind as a possibility, makes me not even want to start another one in fear of it happening again..

I've posted the screenshots below and the save data as well.

Edit: I also realized I somehow uploaded the save file as a notepad document? I'm not sure how/why, but I would be glad to fix that if it's an issue if someone could let me know how.

Hi again.  Yeah, that's a bricked run.  I'll throw this on Mantis for you since this is something that isn't really fair for the players.

Hello! 

Okay awesome thank you!

Np. 

And welcome to the forums

[SourKiwi]

Thanks! I'm really liking the game so far! It's very Binding of Isaac -esque, which is great since that's one of my favorite games - even though the aesthetic (of BOI) gets to me after awhile haha

All the more reason to hang out with us.

For 1.006:

* Changed the logic of using keycards to unlock all doors in the room on the other side, rather than just the door facing you.
** Otherwise a shop/item-room/etc that was locked could take two keys to get "through" to the other side, and if there was literally only one available and that was between you and the boss, well...

Thanks
