Since I went to Build 58414/TS12, I have missing assets in about 20 of my routes. I'm not going to waste mine or anyone else's time looking for them. Already Googled them with no luck. They're not THAT important. So from surveyor I tried deleting the lost assets. Not working. Imagine that. When I hit save after doing so, the window appears saying that my route hasn't changed and doesn't require saving.
