Hi,
Thanks for your quick reply. I've tried your solution and the level works in CPU mode. I don't know whether this confirms or disconfirms your suspicion about the sprite. I've seen it casting spells at me so it cannot be entirely corrupted right?
It is indeed Axebite Pass and there are doing what they do best. Much fun, the forced pace and give it a hectic feel that's a lot more like real battle (I'd imagine) than some of the missions in the original campaign.
Good luck in battle!
