captured ship designs in sea base replaced with a scout

[bvanevery]

I mind controlled a sea base from the Pirates.  2 of the captured ships were these pathetic early synthmetal designs.  They were specific to the Pirates as they had the Marine designation.  I had way too many units to support in the captured base, so I took a nearby Usurper base, to end their willingness to make war on me.  That would leave me a free hand to deal with the Pirates, and hopefully keep the Usurpers from stealing from me for a bit.  I wasn't worried about them mind controlling my sea bases, because I had +3 PROBE, but I didn't have enough foil probe teams to cover the bases at the moment.

I moved the 2 pathetic ships into the captured base and Homed them there for support:

The next year, the ships were gone and instead there was a scout!  I only discovered this 2 years later.  I think the game recycled the unit design.  Somehow attached to the Pirates, and I didn't have any other ships fitting this description.  Odd that the units were substituted 2 for 1 though.  Why not 2 scouts?

Boy I'm just coming up with all the juicy bugs lately.  What am I doing right?  Anyone seen this before?  Does Scient's Patch deal with it?
