Torpedoes and pistols

I am currently using GWX 1.2 until I go back to port and upgrade to 1.3;

I noticed that torpedoes set up with impact pistols explode before impact from time to time: I thought it was a problem only for the magnetic pistol! Have you noticed this?

I can't rely on torpedoes now, this makes attacking convoys dangerous and frustrating .

Thanks for your feed back Kaleuns!

Happens to me also. It is nowhere as frequent as with the magnetic triggers, where sometimes a four-spread never reaches the target, but now and than it happens.
