Not a question necessarily, but today after creating a symbol of a detail, using keynotes to annotate, the file would become unable to open. It wasn't until saving, closing, and trying to reopen that I noticed the problem. I created a new file, referenced in the resources from the corrupted file and then experienced the same problem when trying to reopen the new file later. I tried fixing the symbol and it responded by creating 41 keynote legends(one for every singular keynote) that were completely empty and wouldn't allow me to change what legend to use. It wasn't until I removed the detail with the keynotes that the file was able to open again.
Also, it should be noted that when opening the corrupted files, the progress bar would always stop at "Step 6 of 11: Resetting Text and Dimensions." After that I would have to force quit Vectorworks if I wanted to do anything.
