Brumation conditions: Dry, humid or wet?

[Stefan-A]

This is exactly the problem I was talking about long ago when I saw people were brumating their snakes on wet aspen. Then Stefan basically told me it doesn't seem to happen to everyone else. Well, what do you say now?

That wasn't aspen and this wasn't wet. Come to think of it, this was set up pretty much according to your stated preferences.
