Crash after annihilating the Mamla'ha biMassylim

[removegyros]

Happens to me also, around 251BC

They have 1 town and 1 diplomat, sometimes it crashes only after they lose the city and the diplomat moves, if I kill the diplomat it crashes after the battle (or rather the game hangs indefinitely). surreder_regions f_numidia results in a crash also. Don't know what else to do. The issue seems to be something in the transition to horde mode. After looking around in the script and other files, it seems that there is much more going on that can go wrong than I thought at first.

Is there any good way to debug this? Can I follow the individual steps in the script somehow, as it is run?
