Scheduled space only. Does not occur in unscheduled space.
Undefined or nonexistent variables only. Nil will not produce.

Produces no error of any kind in Arma, not even an undefined variable script error.
Produces no Arma log artifacts.
Vanilla, stable branch.
"%1n" appears to be a critical component.
-showScriptErrors is involved. Remove it and the crash goes away.
Multiplayer behavior is as such:
Any client that crashes in this manner will be considered by the server to be "losing connection" for 90 seconds. Attempts to rejoin the game will append a (2) to the player name and the server will then kick them.
Local servers (servers with interface), will crash.
Dedicated servers do not crash with this issue, though they will kick rejoin attempts until the original connection times out.
