I've found a few... well 'errors'. Nothing important though. Well done. (;
Personally, I prefer staying unhidden. It gives players the opportunity to ask whatever question/s they have.
If I'm correct, you can access the gstorage from LMS maps but you cannot trade the players over there.
Also remember to turn off PvP when you warp to the map. Many GMs just forget to turn it off so might want to make sure.
Since when? I mean giving them 5 coupons each would equal 10 coupons. Considering a single winner gets 7 coupons, I find this quite unfair. Players can just 'organize' a tie per PM and benefit from it. Just a thought, however.
Dispell cancels Trick Dead so just dispell them to see if they lie or not.
