[FIXED B1000] How to lay mines with submarine (submerged)?

[msc]

I tried to lay mines with a submarine (German Type 206). I added different mines to torpedotubes (and also tried to add a new mount "Generic Minelayer-Deck-Pallets" as the Type 206 had a plug-on minebelt.)

However, the sub will not lay any mines as long as it stays submerged.
When the sub surfaces, then it can lay the mines. This is rather useless!

Did I make a mistake in the setup, or is this an error in the software, database or wathever?
Any idea how to get the sub minelaying when submerged?

Savegame file attached.

The MBM-6 mines and a few others should work ok in B972, yes?

Many thanks, your support is really perfect!!!!!

I tried the MBM-6 on the Type 206 submarine, but this did not work in B 792 either.
(I did not try if mining worked with a different submarine).
