Just curious if anyone else is seeing this after the update. In the BoB tutorial scen, Blenheim and Wellington bombers drop bombs, hear the falling sound but no impact/explosion. Currently in midde of a Blitzkrieg scen (Barbarossa), sound file works perfectly for all German bombers. BoB was bomb drops on naval targets but I could have sworn there was still explosion sound? Someone please correct me if I'm wrong
