Hello Wulf,

I have the same flicker on the screen in the Nyx as you.

Added screenshots. It can be seen that the driver camera on the right only shows blackness.

This happens because the functions that run the catapult attach functionality (BIS_fnc_Carrier01CatapultLaunch or BIS_fnc_Carrier01CatapultActionAdd) use "player" and "vehicle player" in a lot of places.

Report with the same glitch

Can confirm. Not processing commands and "Watch:" fields, but also not allowing access to spectator, camera, functions, config, animations and the gui editor.

This glitch happens in BIS_fnc_AircraftCatapultLaunch.
It happens because plane getVariable "bis_launchState" keeps value 1 (successful) after launch.
On the next attach it doesn't wait for the hold button action to actually set this variable to 1.
