gears still shows up in some planes whenever I close them up
Ok so I'm having a problem with the gear of the planes, so whenever I land with any random planes like the eclipse or the Comanche, once I flew away and close the gears, the gears still show up, I don't know why did this bug happen, I think the latest version of this mod which is "Immersive+Vehicles-1.12.2-21.2.0" is broken or something.
.
This is due to internal positional changes in that version that allows for easier pack creation. Will fix in the next OCP update.
Fixed the issue
Still got the issue in latest version. Have only tested Eclipse and Commance from official pack

Yup, because the issues was in the Official Content Pack, not the core mod. When the pack update drops, this will be fixed. But I do thank you for getting back to us here. Very few people do. They just submit the ticket and ghost.
Fixed as of latest OCP release.
