For those "having a new update available" for the MV-22B Osprey by Miltech Simulations in Orbx...

There was a folder naming convention changed by the ORBX Team in the backend, which is resulting in ORBX notifying an update is available for MV-22 nearly daily, though no updates have been released in the past few days.

The best way to solve this issue is to uninstall the product, delete any folders in the community folder associated with the MV-22 and re-install.
