There was no respond in this thread, so im trying to keep this alive:

> Hello! We recently upgraded to 8.0.5. And now we observe a strange import error. When we try to import tags from XML, we get the message “Optimizing imports”, which spins about a minute. After that, the import process fails. It does not depend on the number of tags imported. The error also occurs for the folder that we just exported from the current project. What could be the reason for this behavior? Thank you in advance

I am not sure how many is affected by this.  
"tag export" -\> "search/replace" -\> "tag import" is not working. We have to add all/change all tags manually in ignition 8.0.5rc1.
