ACotGK: Dungeon Generation Bug

I’m currently playing through Accursed Crown of the Giant King as part of final testing. It’s pretty fun!

However, today I ran into an interesting bug. Check out this level:

There’s no way to get to the stairs up!

It turns out in certain levels, it is possible for the random number generator to spit out just the right values, and a staircase can get completely blocked off! It only happens in a pretty rare set of levels, and very rarely even then. To create the level above I had to result to changing the random results in the debugger. However, I did run into it in my playthrough, so it can happen in the wild!

My fix is a little janky, but I _think_ it’s OK. In the situation where we create stairs pointing at a corner, I just flip the direction of the stairs around. That _should_ make it always possible for the dungeon generator to create a path to the stairs.

I should get through my initial testing next week, and start to work on getting some other beta testers.
