I'm fairly new to CoH2 mapping and in this map I've been working on, I've noticed that there's a large amount of impass appearing in places where I have no objects. I'm not sure if there's anyway to remove it. I didn't paint it there and I can't remove it with right click ( I take it all the impass marked in red is automatically added and can't be adjusted. )
Is there anyway I can get rid of this?
Also, at one point I had to stamp my entire map and paste it into a new file to adjust the playable area because it was too small. I believe the problem occurred only after I did this, so it's probably related.
