Lua stack traces don't trigger

Fatal Lua Error: [string "-- Make copies of global functions to preve..."]:30: Uncaught CLR exception at Lua->CLR boundary: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.

It would be great if the bot would detect the inner exception:

---> System.NullReferenceException: Object reference not set to an instance of an object.
at OpenRA.Mods.Common.Scripting.TriggerGlobal.OnObjectiveCompleted(Player player, LuaFunction func) in OpenRA/OpenRA.Mods.Common/Scripting/Global/TriggerGlobal.cs:line 183

and highlight it.
