Oh and theres one bug in this lastest version I already know of... and I dont think it's caused by anything Ive done.
The lift in the lava cavern room goes a bit funny when the crusher in the mancubus pens is activated. The lift will not descend properly until the mancubuses are killed.... it kinda gets stuck and shimmies up and down a bit.
Dunno why that is though
Its not a big deal as nothing is attacking you at this point so you just need to wait there on the lift till the crusher as killed the monsters

Whilst on the topic of crushers. I find that it takes too long for it to kill the monsters in the pens. Especially when they are tough ones like Barons. Is there a more deadly action I can use to kill these monsters more quickly?
