How to make duplicate item Canaan/Pet forest using Maintenance Critical Time

This is the weekly maintenance time in Canaan.web.id
at 8.30 the system will broadcast message and say to player to logout to avoid any error.
then some player who keep playing and not logout their character get some error, from missing the experience they got and losing some item, but some player who trade in the critical time get their item duplicated

This cause of the system will not save any change in critical time, we never know what is the critical time to server before its totally shutdown, but the system will make rollback any change to time between critical time, and we can use this critical moment to make duplication of item and pets.

Theoriticaly :
- Trade item from first character to your second character on critical time,
then  logout your second character to let system save its item/pet
- keep your first character standing until the system totally shutdown
- after the system finish its maintenance, login both your character, and you should own same item on both character. (if.. only if you are trade in the right time)

have fun...
