Something weird has seemed to have changed at some point in the last few updates.
The guns on my camel have become insanely powerful, or the AI planes have been changed to be composed of thin glass.
It doesn't seem to matter what map I create a Staged Mission on. All my lethality settings are 1.0. It didn't used to do this.
See attached film on NDIsles offline Staged Mission. I set it up to demo this. One single ping blows each one up. It is not a fluke. Every time.
[edit: maybe 2 pings but seriously outa-whack. ]
