Bug in the city Church: the first character you put through the base-level (only available) lust removal spends the 50 gold and has the appropriate amount removed. The SECOND character you put through the process AUTOMATICALLY spends 100 gold (if you have it) and has twice as much removal, whether that is what the player wanted or not! I'm not sure if switching back and doing it a third time spends 150 and triples lust removal but it wouldn't surprise me.
