No, I haven't encountered this since the last update.

Extra info: this was on MP, wasteland mission. Two separate servers. I tried to reproduce in single player by playing a showcase - without issue. The MP server consistently triggering the error was: "BalotaBuddies | Arma 3 | Wasteland" "404 Wasteland 1.05 Alpha"

That's happened to me, but at the same time I see the display driver has crashed (notification popup in tray). I'm on catalyst 13.1, probably a driver issue?
