No warning on duplicate content tags

[Evolution0]

Yesterday I put together an OIV installer (package format 2.2) for an addon car, for the life of me I could not figure out why it just didn't seem to appear in-game even with no warning that the install failed, I also seemingly could not get a mods folder install option, only a direct game files installation.

After taking another look at it today I just happened to notice I had two sets of content tags wrapping my content, OpenIV does not seem to error out or warn you if this is the case and just proceeds to install.. nothing.
