note really sure if "tag collections" owuld fix it.. BUt I will try it. Right now we cannot move away from Moodle 2.7 so I will have to work around that.
If I have a tag table like:
tag.name tag.rawname
TGName TGRawname
if we restore this in another server with the same as above tags, we get:
tag.name tag.rawname
TGName TGRawname
TGRawname TGRawname
however, when i restore the course again on the second server, there are no new tags created but the existing question is tagged to
tag.name tag.rawname
TGName TGRawname
TGRawname TGRawname <------
