[Map bugs]2 bugs on DM2 maps 19/20

[nwbeeman]

On Doom2 Map 19, go through the first two doors, you should see a door behind a raised sector that looks like a switch. Go up to it and press use. The door behind it will open. Is this the intended behaviour? You can also press use repeatidly to open/close the door

Also:

On Doom2 Map 20, goto these coords and look at the walls of the room, you can see through them.
Z: -2118
Y: 36
Z: 16

I'm assuming its the GL nodes, or the fact that I have an ATI card

More likely however, they're mapping bugs.

Did someone see a barrel in the wall?
