How to build 'obsolete' UUs in a PBEM?

posted this piece of junk on CFC when CDZ was down, no answer yet...:(

Here's the situation:

I'm 2nd human player in a 3-player (plus 5 ai) PBEM, in 2nd slot as Sumeria.

I could build pikes (iron online), but no GA yet. So both Enkidus and pikes appear as build options. But everytime I order an Enkidu in a 10spt city, I wouldn't get it in the next turn.
Instead, the city automatically switches to a stinking pike.

In SP (at least in vanilla) the thing used to work (not with queued units, though). What's the deal, is it -maybe- depending on the player slot?

Don't know if it's the same issue, but I've VERY recently experienced problems with obsolete UUs too. It would let me build the UU, but change it to its upgraded unit everytime I'd discover a new tech. And of course in PBEMs you're not allowed to have a word on it during the IT. [mad] Sometimes Civ makes me go [rant] (but Beam, don't look at my spoiler :D ).

Weird, I've never seen it. [???]

seen that, too: if you discover a new tech the unit build gets adjsuted, just like when you discover the tech that gives the new unit.
