SERVER ERROR
As reported here:
https://feedback.bistudio.com/T158372
cfglimitdefinition.xml has <category name="vehiclesparts"/>
and
types.xml has <category name="vehiclesparts"/>
Notice that vehicles is plural. However
mapgrouppoto.xml has <category name="vehicleparts" /> <- where vehicle is singular.
This causes Server RPT to show the following error:
[CE] :: Unknown category: 'vehicleparts'
It has been doing this for ages.
FIX:
In mapgrouppoto.xml replace all instances of "vehicleparts" with "vehiclesparts".
