In 8.1.3, I have to use the tag editor in order to change casing on a tag. the system.tag.rename() isn’t doing the job.
Can you rename it to something else and then back to the right name with your different case? I find I have to do that even in the tag browser, and I think it’s a Windows OS thing. I haven’t tried, but I think Linux would be able to do it as it’s natively case sensitive
Thanks Nick. That makes sense to me. I ended up doing what you suggested by add TEMP to the end and removing it afterwords.
