clicking 'yes' should generate a popup reminding people not to report bugs unless they confirm it exists in the base game...in which case specifying what mods you have installed becomes irreverent

You only need the two sides.  it will look like the railings provide their own floor but they dont. Thats just a highlight of the tiles underneath it.
 
 
You also already made your own corner in the pic above. If youre not satisfied with it then maybe use one of the corners thats just a stick to fill that little gap.
Just keep aligning the edges with the fence as you were doing in the pic.

After placing your emptyoutside "room" click on the place wall tool on the toolbar (just underneath view and building menus) and then Exterior Walls in the tiles and furniture pane on the right, select "none" from the list below and draw your "invisible" walls where exterior walls have appeared.
And your main roof shouldn't have an emptyoutside room def on it as it sits above the rooms of your building which will already have room defs, so the emptyoutside room def is not needed.

Go through everything and make sure it works / nothing is missing, again.

I added a bunch of my residential and commercial zones aswell.. alot of building variety to be added to a map.. .I hope someone adds them to a map, it be cool to play in those buildings. 
some buildings might be missing room definitions, dont remember, this pack was abandoned months ago and I believed it was better off if the community had them.
 
====I strongly advice not to edit the buildings, they are made for the player to struggle to get in, Let the player figure out how to go in, them. some of the buildings blocks are straight puzzels with many dead ends====
***DONT FORGET TO INSTALL THE CUSTOM WALLS IN YOUR 1X 2X FOLDER!***
 
 

I think we'll look into stuff like this, but I doubt it'd be in the first release.

Would be better, if they make unique "destroyed" sprite for that thing.

How are you going to deal with small road obstacles such as road cones and fire hydrants? Realistically a car and push right past a road cone, but they are getting blocked completely in game.

Instead of blocking cars completely, maybe mailboxes could be replaced with scrap wood and metal after they're hit?

The Collision Update Video is REALLY great - very nice!! 
 
Will you chance the mailbox so that it will be destroyed (and the car REALLY damaged)  if you drive "through" it instead of blocking the car?
 
can't wait to get the vehicle in IWBUMS and 38.26 out in the open (shouldn't that have happened last monday already?)
 
really nice stuff
