Disappearing Kreigsmarine

[Jimbonsx]

Morning all.
Playing a PBEM game as Axis, I positioned a BB in hex (52,12), at the approaches to the North Channel (off the coast of Northern Ireland). During 'convoy movement' I was able to see a convoy moved directly into hex (52,12), causing my BB to disappear - literally become not visible. The convoy remained intact and in situ and my opponent, not aware of anything unusual, arranged his DD escorts around it during his turn. My turn came round , I couldn't find my BB but of course I knew where the convoy was so I attacked it. I felt honour-bound to relate to him what had happened and asked him to 'BOLO' for it. No casualties were incurred by either player at the time of 'collision' and the 'Casualties' and 'Forces' screens showed no change in the 'Naval' stats.
This has happened to me before in a hotseat game, and I'm wondering what's happening?
In this hotseat game, the ship (a DD this time) reappeared a few turns later, to my relief and bewilderment.
So 2 questions -
1) What happened
and 2) How can I buy more invisible BB's?

Update:
My next turn, my BB still hasn't appeared, although if I press <Page Down> to find the next unit to move, the game acknowledged (52,12) as having 'something' of mine in it, but still refuses to show my unit.
Thinking about editing the map to rename that area the Bermuda Triangle. That or rename my BB the Flying Dutchman.

Update:
Next turn, still no BB, <Page Down> still insists there's something there.
Getting worried.

Nowhere can I find how to use the rail Movement

There is a rail icon that will highlight in the lower left corner where the unit stats are when you select the unit you want to rail. If you're not adjacent to a city or don't have rail points left then the button won't highlight.

I've seen it happen before when naval units disappear. It has been impossible to recreate. It seems to happen when a convoy moves and for some reason ends up in the same hex as an enemy unit. Normally the target hex can't be an occupied hex. So why this is happening is puzzling.

Others who have had this problem got the naval unit back when the other unit occupying the same hex moved. However, you claim that the unit seems to have disappeared for good. However, the name is there.

To check that out I need to have a save game where the problem persists. Then I can try to find out where there unit actually is and why it's not shown. If you give me the name of the unit then it would be easier to find. Send me an email to borgerb@online.no
