Thanks guys.
There are many building entries which have been lost, although some data for the buildings does remain. Many of these are shorter buildings, and since this is
SkyscraperPage and a diagram website I have been focusing on restoring the most important buildings only. It will be tricky to restore all lost entries properly, but I'll see what can be done. Most likely a special editing form will need to be created, similar to the one for drawings.
350 of the 1800 lost drawings have already been restored. Thank you to all who have entered data for their drawings, and I am sorry for messing things up like this.
On the odd chance that any illustrators who should have didn't get this by email you can visit this page to see if you have drawings here. If not then you have nothing to concern yourself with.
