i thought you needed to have movement left to be able to withdraw? get them down to 0 movement, then kill them.
On a side note: there's an issue with the national wonder limit on OCC games. The normal limit has been changed to -1 (unlimited), however the OCC limit is still at the normal BTS limit (5). Adding the following line to GlobalDefinesAlt.xml should fix this:
<Define>
<DefineName>MAX_NATIONAL_WONDERS_PER_CITY_FOR_OCC</DefineName>
<iDefineIntVal>-1</iDefineIntVal>
</Define>
