Ever since V2 is released, the trees are either invisible or broken.
On Classic HD the trees are rendered with strange orange layers inside.
On Classic HD with environment set to Reforged, the trees are rendered as they should.
On Classic the trees are completely invisible.
This bug hits both the official and custom campaigns.
Unless the map supports Classic HD with environment set to Reforged, it’s just not playable. and the Classic graphic experience is totally ruined for having the trees invisible.
