Hi.

My workers had collected 43 Rough Translucent Crystals that went to Velia storage.  I took them out into the inventory of the Sorceress.  I then put them into the central market storage and the stack changed to 1 crystal.  

I carried out the following actions to see if the stack would refresh back to 43 crystals, all of these actions failed to rectify the problem.

Took it back to inventory, remained 1 crystal.

Put it back into Velia storage remained 1

Returned to central market storage, disconnected and logged in with Witch, (Located at Altinova) took the crystal out to inventory and it remained 1 crystal.

Put into storage then tried central market storage @ Altinova and the stack still remained 1 crystal

Tried processing stack using heating - message insufficient number of crystals to process.

Attempted to list on the Central Market - message You will sell [Rough Translucent Crystal] x1 

Tried closing game client and restarting PS4 Pro.  Logged back in but stack is still 1 crystal
