Bug - DCSW 1.5.8 Stable - Lua Config error when slotting into forward observer

[Igneous01]

When you slot into a forward observer slot, you get this error in the log

 

	13874	01014.821 ERROR   Lua::Config: Call error occupy_player_slot:?:0: attempt to index field 'route' (a nil value).

 

I dont see any visible effects or issues in game, but it probably shouldn't be trying to load a route for a slot with no airframe.
