Attempting to deal Player **Player** (6)
Deal request failed (unknown error 5).

This is happen when I deal with a player is opened the storage.
I want to deal with a player which open storage because I have to transfer large amount of item to another player, if cannot deal with a player which opening the storage this will used up a lot of zeny to open the storage.
I found this problem in mRO(Malaysia free prontera server)

Anyone know what is the problem and how to fix it?
I'm using the latest 2.0.7 openkore, I have tried the older version(2.0.5)(2.0.6) but still the same problem occur.

If your server doesn't let deals while storage is opened, then it also won't work with kore.

Dealing while kafra is open has been disabled on many official servers because for the longest time, this has been the source of many duped items.
