Deleted groundcover instances are not deleted in game

Tested in OpenMW-0.47.0-RC7

I have a few gass mods I made, one is an ESM file and the other one is a ESP file which requires the ESM file.

The ESP file deletes some of the grass from the ESM file but when I openmw.cfg to the following...

no-sound=0
groundcover=MyGrass.esm
groundcover=MyGrass_Patch001.esp
fallback-archive=Morrowind.bsa

The deleted grass objects in MyGrass_Patch001.esp are still showing in OpenMW. This is not the case when using the Morrowind propetary engine with MGE XE.

Please allow for having a load order for groundcover were deleted groundcover objects will be deleted and moved groundcover objects will be moved.
