Quote: These tags are meant to be a nearly completely (99.9%) bug free singleplayer tag set for your complete modding needs.
I say 99.9% because there MIGHT be a bug or two I missed, but if there are I never found them so they're likely not a significant issue.
Just install this tags folder and you should be good to go.
If you get a crash in sapien for any campaign scenarios just make sure you removed any script related instances in the .scenario and the map will open fine.
Then just recompile the scripts. For more detail on this crucial step before you start modding check the common CE errors and fixes
document I included. Have fun guys!
This is the description of the tagset that you downloaded. It tells you to remove any script realted instances in the .scenario tag, so that is what you must do. Also, it would be better to use the HEK Plus in order to obtain the campaign scenario files, as a lot of the tagsets on this site, tend to have missing tags or have other problems.
You can download the HEK Plus from here:
