problem with "open backpacks" and "Resetbackpacks"

[Bbotone]

macro command "open backpacks" and cavebot command "Resetbackpacks", when you have heavy lag, it will open the backpack, but as lagged it will try to open the backpack twice, resulting that when the backpack to be oppened appears, it will be closed with the second opening try.
It causes a lot of wasted time opening and closing the backpacks, it should have a delay to wait to the backpacks to be opened.
