Yea, people always "remember" things. Perhaps you remember looting a poison dagger from minotaur too?
You are the one "acting like you fucking know everything" actually. I'm not acting, I KNOW the info I gave in this case is 100% correct.
Your "proof" movie (24:20~) was recorded in 7.6 or 7.7x version (judging by sprites) and at the time your pot/chest would not even block people from going up through 3 parcels anymore. Those guys were just noobs to think they would prevent anyone from using levitate with these chests.
Here's a movie that I've just recorded on the original stolen Tibia server, and just like I said: neither blocking the roof or teleporting yourself worked.
Anything else, mr. "wanna go 100% retard"?
