basically they get half locked out by the servers anti-flood system. They are not at the full retreat state but still get rolled back when they loggout. This means they can trade items to other users and relogg, thus "duping" them.
There's no real fix that will eliminate duping entirely.
But some actions can totally discourage players from doing it.
- disallowing dropping items from inventory
- making bought items to take full or half stack in inventory
- active GMs
^rbb138 has wrote script that finds succeeded dupings (I haven't tried it as i don't run live server yet). It do't auto-ban players, but if u got some programing skills, it shouldn't be problem to tweak it abit.
If u don't - here's log viewer (credits to Kenpachi ™). If rbb's script finds succeeded dupings, u can check player's tradings by it.

that was i know, maybe some one have other way to dupe, hope they can share it here, and we can find a way to hold duper's.
I wonder if duping is possible on PWI and what kind of protection they have against it...
i think it was posible, if you have a lot of cuby and enough to buy 60 slot loudspeaker :lol:Quote:

What exactly happens when you go into retreat? Do you get a message? Is the message "Server error, please log off and try again"?
In PWI, when you get the server error, you cannot drop anything, I haven't tried trading...
id request shutting up about this subject, robb from deva has created perfectly good scripts/methods to at least close in on the situation, doing areas such as:
- Removing Item Mall
- Disabling drops
- Rare items only being capable of stacking to 1
- Higher bandwidth servers
will prevent this, those who get past all tht then get on the retreat logs as to which u create auto-ban scripts. Job done.
im assuming your not getting the point of this thread... and two, anyone that asks about how to do a dupe or how it even works. GOOOD LUCK even getting an answer to that, as most people that do know will not discuss it on here. as its super annoying. i actually wouldnt be surprised if someone was to get an infracion for asking even how a dupe works or how to do it in detail. if you dont know. then dont ask. stick to the deving of it. plus this has been discussed probably what. 500 times....Quote:

ive been hearing rumors about pwi going to basicly a Private style server and shutting down there botique shop cost system? this cant be true. if anything they'd be shutting down permanently, i have noticed its not as active as it was about 6 months ago since the attack they had on them, and that they have some new game out. anyone else hear about this?!
and ya it would be nice to have a stable fix for it.
i dont see why you cant just add a 2 - 3 second delay on all purchases or drops etc. 3 seconds is nothing, could probably get away with 1 second.
just enough so the system can keep up and cancel the dupes. and even then i wouldnt have a clue how or exactly would be needed to do that and how well that would work
what attack? share please.Quote:

i remember when the attack happened i only saw about maybe 50 people on (sanctuary) climbed back up but still way less then there was
They had DDoS attacks :)
Lol listen to yourself LMAO you heard a RUMOUR dont go spreading it further, PWI arent in any loss with PServers, the best PServers out there are the Brazilian ones for number counts of players and even then they dont cause a threat to PWI, plus if PWI were to do this you could fuck them in the arse very hard.Quote:

also pwi has lost over 70% of their players, have you seen it within the past year, its reduced HELLA (but thats probably from the tideshit class and the earth sniffer class (both the biggest downfall in PW releases)
just my opinion
dupes been fixed in offical since 1.3.6, im not sure how it was done there though.
i still think it uses the game anti-cheat daemon.
But everything about its characteristics points to game server core (map GS)
