Car Tagger not working

Hi, I'm trying to use Car Tagger <kuid:522214:100525> and 100526 on UMR 2016, and it doesn't work. If my memory serves me, there was a limitation on the number of industries, beyond which, the tagger just wouldn't work. Is that the case?

It shows the rolling stock, etc, I just can't click "tag" and have anything appear.

Any alternatives that work?

I was trying to use it with UMR 2020 and it worked when I clicked on "tag" for some types of cars, such as boxcars. However, when I clicked "tag" on an acf covered hopper, it didn't do anything and gave an error with the red bug icon in the bottom right corner. Looking at the error, it says it is a script timeout error.

Update: I implemented a fix for the timeout issue with the Car Tagger rule <kuid:522214:100526> and worked with kenrouf to get the rule on the download station updated with the modification. It is working with UMR 2020 now.
