Hi,
Sometimes tags become bad quality and their value is Invalid Expression, these could be tags that have been working for weeks no issue and its only basic writing a value to them and displaying it. Restarting the service won't fix this issue, neither will trying to change the value in database spy.
I removed all usage of the bad tags and then try to change the value and it still doesn't change, how can I revert bad tags? Any way to see how they became bad in the first place because I can't see what has caused it. I noticed it happens most after the service was stopped and started again after making changes on something unrelated.
Any help appreciated this is driving me mad.
Note: Creating a new tag and updating all positions will fix the issue but another tag with become "bad" some unknown time later.
Is it possible to manually delete individual tags as well rather than remove all unused? I'm wary that I could remove unused tags which the system thinks aren't used but they are, how reliable is the "remove unused tags" function
