Far out. I'm checking and modifying "location" in the ARE file at 48 (size 2), not "area type" at 14 (size 14). 14 does have a rest toggle, but since I have to read 48 anyway to make sure it's actually indoors, since the default position of 14 is to allow rest, but with 48 as indoors, not allowed occurs. The weird part was converting to binary to figure out where to put the 1 for the BAND/BOR (which I also switched initially). The example in weidu was much more confusing, though, being usability for items.
Yus. I don't know what I'm going to do with all these new powers. Probably better to start at lowest expectations.
Next up is cycling through Actors and only enabling rest if hostiles are part of the area (at least for a little while). Don't want every indoor available, but the ones where you clear enemies should be.
