My tags don't change

I have an issue with my tags.
I have script which runs every hour and affect these tags but they don´t change, it seems like their´re static but they aren’t.
I also tried to change it manually but this doesn’t work too.
The weirdest thing is that, this only happen in a speciffic project.
I would like to know if anyone else have experience with this.

Do you get an error message when you try to write new values to the tags manually? Is there something else writing to the tags that’s overwriting your changes?

Also, are you getting errors in the logs from the script that is supposedly writing these tags? Consider adding some logging at the end of that script to demonstrate that it really is running all the way through.

I have not received any errors and the scripts so far are running correctly, it only happens when I make a change in the UDT ,is frozen, the memory is almost to the top, do you think this could be?
