Right. I officially had my head stuck up my ass the whole time. Turns out the problem was I hadn't figured out the correct syntax for temples used in the descr_strat.txt (ie. "temple_of_XYZ temple_of_XYZ_*level*"). Fair enough.

Except I could have looked up the bloody BI descr_strat for the info.

Gah.

Well, the damn thing works now. Thanks to everyone for helping out, it was quite useful.
