Yup, I'm sure. Appearantly, the key disappears if you enter the cemetary before the Gardens. Weird. Anyway, with a lockpick skill of 5, I could pick them open instead.
Thanks. I'll be sure to pick that bed up. Sounds handy.
Yeah, it's a shame it's buggy. Can be pretty frustrating. I've also encountered an annoying crash sometimes when I try to quick save...
