Plant crashed and I lost a couple of hours of work. Trying to recreate it, I can not use the tags of the pump and tank because it says it already exists, but it doesnt. The line numbers I created after the save and before the crash cannot be recreated either. I enter a new line number (one I lost during the crash) it accepts it, but then as soon as I run a line, it labels it as 'unassigned.' Somebody please help.
