Set up a single mission to insure you get stones thrown at you.
:D

That would speed up testing.

As a side note..............
Increased ASW has duplicate ID's in the bomb.zon file.
Nodes 10 and 14 are duplicates.
Both point to the AirTorpedo in the bomb.dat file.

I did just that. Set up a test mission and it worked fine without the Increased ASW and Realistic Depth charge mods. First time I've ever seen a hedgehog launch.

Will reinstall the ASW mod and check it a bit later.

EDIT: Reloaded an old campaign save and tested. Hedgehogs worked fine in campaign mode vs. a single mission.

Still need to check it with the ASW mod.
