Traders can't start new route

[Player of 0AD]

In this savegame, the kushite traders (near kushite market) can't be commanded to do a new trade route. Mousing over markets gives error messages.

In the match, the initial market was destroyed or conquered while the traders were on tour.

I will test this in Alpha 9 (where trading was first introduced), to see if this is an regression introduced in recent patches.
