The Yolona blueprint replacement breaks the visuals from the unit's script and makes the weapon unresponsive since it uses WeaponRepackTimeout
instead of RackSalvoReloadTime
.
FAF's Yolona was changed to not have the weapon unpacking typical of other launchers since it doesn't need that to control its fire rate: https://github.com/FAForever/fa/pull/5758
Edit: Using MuzzleChargeDelay
instead of RackSalvoChargeTime
can also make the launcher not respond like you would want it to, it'll fire in 5 seconds regardless of the launch order being cancelled.
