Many of my graphics in various Art Libraries are showing as a black circle with with a slash. When I drag these graphics onto the board, they do not get placed.
The art libraries are stored on a network share, if that matters.
Are these recoverable? I did reboot after in installed 1.4.05.
Symptoms such as this can often be the result of storing the files on cloud storage or a network share. As you’ve said that these library files are stored on a network share I’d say this is the most likely reason for what you’re experiencing. Do you have any backups you can restore and check to see whether they’re usable?
