Actually once you post a thread there is no way to delete it. All you can do is edit the post and the title of the thread. For example, you could change the thread title to something like Nevermind. But it will still be there.I was actually going to delete my question when I checked and saw no resources were returned. You just lose culture which makes sense.
I think if you leave a trail of snacks to the delete button for the Powers That Be, it might work.Actually once you post a thread there is no way to delete it.
Every time you upgrade streets you are completely replacing everything. I do road construction in the real world. To completely redo a street: mill out all the existing asphalt, tear up any curb and sidewalks and replace those, and regrade the road is actually a more intensive process than just building a new road. Because you need machines and equipment to do the road demo and a lot of dump trucks to haul off the old material. All this has to happen before you can start rebuilding the road. They really should charge MORE to upgrade a road. LOL
