Dedicated Server Multi Class Races

All,
Is there a way to directly contact Reiza?

Otherwise, trying to set up a multi class race on the dedicated server with the following lines:

// Initial session settings, see /api/list/attributes/session for the full list.
sessionAttributes : {
// Whether the server controls track selection. (0/1)
"ServerControlsTrack" : 1,

// Whether the server controls the vehicle class selection. (0/1)
// Flag FORCE_SAME_VEHICLE_CLASS (1024) should be also set for this to make sense.
"ServerControlsVehicleClass" : 1,

// Whether the server controls car individual vehicle selection. (0/1)
// Flag FORCE_IDENTICAL_VEHICLES (2) should be also set for this to make sense.
"ServerControlsVehicle" : 0,

// Race flags - bitfield consisting of many flags. Add flag values to get overall number required here.
// See /api/list/flags/session in HTTP API for the full list. (-1610087912)
"Flags" : -1722909976,

// Grid size & number of slots reserved for players. Remaining will be populated with AI. 32 is the max setting.
"GridSize" : 6,
"MaxPlayers" : 5,

// TRACK. See /api/list/tracks/ in HTTP API.
"TrackId" : 1080325116,

"MultiClassSlots" : 2,
"MultiClassSlot1" : 1347575036,
"MultiClassSlot2" : -1710882048,

But nothing happens. Which ever class the host selects is the only available class to other drivers. I believe I have the server controls track and class appropriately.

Thanks
