I just returned to DR, and I've been playing around and doing a lot of looking stuff up, which usually means I'll randomly hide while hunting if I want to check something out. While doing this, I noticed something weird. SLS stops draining mana when you are hiding. Is this a bug or feature? I can unhide and it will start its small drain over again. I included a bit of log to show what happens. After I hid, I had two fully attuned messages and then nothing.

A shimmering shadowy sphere drifts in with a hiss, following you.
