Expeditionary Forces spilt and lost

[unmerged(129155)]

I had this happen in two games now. I send an expeditionary force to another nation to help them in a war without me having to declare war and actually enter the war. Then later I discover that the force of seven units has been split and my expeditionary force has only 4 units and the other 3 units now belong to the other nation and I can't get them back unless I edit the saved game file. Interestingly the last time this happened the unit was split by the type of unit. e.g. I was left with the Inf-guard units and they "took" the inf-engineer units.

I think it's the splitting that seems to trigger this and I don't think you can prevent the splitting except by sending only single-division EFs.
