[Dolju]

Hej it's my first post.
I have little problem. I added new wall in ds1edit Loader. In the editor works correctly problem is in game. Appears green tile. It's not VIS.

• lvlTypes = akt1 town file 11
  Dt1Mask = 1983
  files lvlTypes and lvlPrest in global\excel.
  file newwall Global\Tiles\Act1\TOWN

What I did wrong???
