VII boat torpedo loading bug?

[It762]

Hi there! I've read other posts about the torpedo loading problem already, so I do not expect a fix But maybe someone has an new idea! The situation: Expended all internal and external torpedos, expect one external stern torpedo. The external torpedo was moved in the internal store manually (auto is off) then i tried immediately moving the torpedo to the stern tube, which does not work. I also do not get the message (ballon help when holding the mouse over the torpedo) that i do not have enough man). When trying to move it just jumps back. There enough men available. (some exhausted, but the green bars are fully filled). I tried moving men in and out, and into front and stern tubes. Also tried the silent running enable and disable. Now iam out of ideas. Also tried to leave the thing on auto.... Stock sh3 1.4b plus damage mode, traffic mod, radio mod , torpedo gfx mods, flag mod, moose measure mod....
