ToME: the Tales of Maj'Eyal

I'm noticing that while on auto-explore or while resting, I no longer have my resting/exploring interrupted because of stealthed enemies within sight. Which makes sense, and makes enemy stealth a lot more problematic, but which also feels a bit bullshit when I'm playing a squishy caster class and an unseen Orc Grandmaster Assassin walks up to me and one-shots me with an instakill combo while I'm halfway through resting.

Anyone else experience this?

you expect a grandmaster assassin to give you a chance to retaliate?

Stealth was made to give consistent results in one game turn, so an enemy no more needs to pass 1000 checks for you to not notice it.
That's a pretty old fix, though.
