I went into the shelter basement, took LSD, waited until the hallucinations started, took sleeping pills until I was tired and slept.

I think the issue here is that in MonsterGenerator::get\_valid\_hallucination()

```auto

```

rng(x,y) is [x,y] so sometimes it will access outside the bounds of the array.

Inclusive on both ends, right. Accursed off-by-one error!

I’ll admit, that was my mistake. I’ll get it fixed ASAP; thanks for reporting.
