@nonebutMau Dodo uses SEAPLANE as its handling, and that handling data only seems to exist in a single handling.meta file.
The vehicles.meta data seems to exist in 3 vehicles.meta files but again, not sure of their exact location. If you just want the data extracts for those, I can get them for you no problem. If you need to know the exact location, that will require a bit more messing about.
Or you can do the same thing I have done. create a folder on your desktop, search for handling.meta in OpenIV and then extract all the files it finds into that folder. Do the same with vehicles.meta and then use Windows search to find the word SEAPLANE (all in caps) and that should highlight the files with that text in.
