FreeRoam GUI - two errors

[XetaQuake]

hi, i get on the FreeRoam GUI two errors

this are not so important because all work too,

but it is a little bit spawn in the log...

here are the 2 "errors":

ERROR: fr_server.lua:303: attempt to index field '?' (a nil value) 
ERROR: fr_server.lua:320: attempt to index field '?' (a nil value) 

and here are line 303 and line 320:

Line 303

  if g_VehicleData[source].timers.fire then 

Line 320

  if not g_VehicleData[source].timers.fire then 

the errors are appearance when a player go in a vehicle or exit a vehicle

somebody a idea to fix this?

And it can cause blip conflicts. I completely removed it's map because it was spawning a blip a 0, 0, 0 and making everyone's blips look like our admin blips.
