I dont believe Ive seen this error before. and it is keeping me from saving my project. I have been working on my project all day and just a few minutes ago, when I try to save like I have been doing throughout the day the below error pops up and keeps me from saving. I am the only person who has touched this project.How can i not be the owner(plus i have no clue what lock it referrs to, there are no locks being used. Any ideas of what may have gone wrong?

I believe this is a known issue that has bee fixed for 7.5.2, but to be sure can you check the designer sessions status page on the gateway and see if there is a reference to the lock 653 pertaining to Client Tags? ---

This has been fixed for Ignition 7.5.2. The work around is to make a new client tag. This should release the lock.
