i think you are kind of misunderstanding mu question, but, about you first point -
1. yes i know lonas virginity will make the cost higher. so the first times are always expensive.
2. the problem im talking about is the TP gains issues and bugs, AFTER the sex sequence, ie, when lona starts her s*x then at the end, when the npc c*ms, after that the npc pays and teleports to their respective positions in the tavern. Im saying that, after the npc pays in TP, the TP with lona reduces, by a large amount.
now that mr. annulein has said that the trade points gets converted to coins, i might have to check it out.
anyways thank you for the response.
