Pstemarie,
Since you have so much going on with healing and Q, why not add just one more tiny thing to the list '> ?
The mines and caverns set has a quirk in it- the water/floor edge tiles walkmesh seems to let creatures drop down under the water,15/20 feet?, as well as lets them move around (back and forth) along the floor edge. I saw this happen with a NESS spawn- 3 creatures at once. It looked as if the spawn pushed 2 of the 3 right into the water, where they dropped down. I also saw it happen in the Q OC, chapter 2, the troll caves. The creatures can be targeted with ranged weapons/ spells, but can not be hit with melee weapons, in effect acting much like the raise/lower cliffs in the rural set.
Perhaps adding a way to get down, and back up like the cliff stairs in the desert set could be a unique alternative to just fixing hte walkmesh. An underwater cave door, could be useful.
Did I say one thing? maybe another if you feel up to it, and your pain meds aren't too strong: The Q forest set, love it! but it could use some slopes for the raise/lower feature...
Get well soon!
