So I've noticed an issue in MP in 1.5, and this has been an issue i think since 1.2.
When you lock an enemy plane with the radar the enemy plane gets a radar lock warning, you then turn on your EOS and turn your radar off, now you are tracking the enemy plane only on EOS, the tracked plane continues getting a lock warning until you completely disable the lock, then the lock warning stops.
After that if you lock him just with EOS he will not get a lock on warning.
Can anyone confirm this?
It's a bit hard to test since it requires someone to help you.
