Four of the 3.75m subassemblies, two from the Stock Extras and two from the FAR extras, have typos in the parts which prevent them from loading; this is presumably from an earlier iteration when the part itself had a typo which has since been fixed.
Searching for WildcarXR and replacing it with WildcatXR fixes the issue; no problems with part alignment as far as I can tell.
