void CheckConsistencyOfArticulatedVehicle | ( | const Vehicle * | v | ) |
Checks whether the specs of freshly build articulated vehicles are consistent with the information specified in the purchase list.
Only essential information is checked to leave room for magic tricks/workarounds to grfcoders. It checks: For autoreplace/-renew:
