Please verify first if:

• V1 is fully uninstalled,
• Reinstall the main scenery,
• Check if any other Irish scenery is installed that may lead to the problems,
• Clean the cache and reload the simulator.

We’re unfortunately unable to verify those because of limited debugging possibilities for developers. However, this may be also caused by the planes and other addons sharing console resources.

We suggest making sure, that everything is up to date.
