Where Hashtable of Photon Stores Data

Hi gddwms.

Putting data into a Hashtable is a pure local operation with no networking involved at all.
You need to pass that Hashtable to opRaiseEvent() to send it to other players.
Storing custom data on the server is not possible out of the box (however player data, room data, properties and the event cache can be stored through webhooks in Photon Turnbased). To achieve that you have to modify the server code (which is currently only supported with Photon Server, not with Photon Cloud).
