Another possible bug in the SA-2F.

If you launch a missile with the proximity fuse off and with the switch in the approaching target position, and then after launch you move the switch to the receding target position, I think the missile is still detonating like it was set to detonate on approaching targets. And vice versa.

I'm not sure if this is a bug or if it's how the system works. But I thought I'd mention it.
