Just to be clear regarding the nv fix, do not use the envsim file included in Stiebler's patch.
If you want to use his envsim file with nv instead of H.sie's, only use the Stiebler envsim file from the NYGM site here.
In short, to have nv use either:
-The envsim file included in H.sie's patch.
or
-The envsim file from Stiebler found
here. #10 on the list.
These are the only two envsim files coded for the nv patch to work correctly and either one is required for it to work correctly. One must also enable the nv patch in the options selector used with H.sie's and/or Stiebler's mods.
