Symbol disappearing from file without a trace in General Discussion Posted June 21, 2012 This is happening to me to! I have some hatches that don't have names and won't let me use or name them, they appear to cause problems with other files referencing this one. Or if someone else in the office opens my file with theirs open too it screws theirs up or quits. I also have a symbol that has a piece of text linked to a record. It is a door tag, and there are a hundred of them throughout all my design layers. The record associated with this tag keeps disappearing out of the file completely (or shows up without a name and does't function like the hatches) leaving the door tag symbol unlinked and the worksheet scheduling all the doors empty. No idea why these resources are corrupt and why replacing them eventually leads to the same problem.
