As a matter of information, we've had a long-standing CTD/freeze when certain mixes or numbers of a certain unit are in battle. The loading bar either hangs or it goes through to the battle, the camera overshoots the general when it zooms in and then everything turns into sky terrain and goes slow or freezes - though ocassionally it works too ;) Even when it did load the number of men per unit would differ for some weird reason.

We - thanks to Xerex - have eventually pinpointed this one-known CTD of Fourth Age. We removed the Darth's descr_formations_ai.txt and replaced it with vanilla. The unit in question was a chariot.

It perhaps should be said that Darth cannot know what weird things we have done to our chariots, but nevertheless the formations cause the CTD/freeze in some way we have not yet fathomed and if we cannot locate it we may go to vanilla and maybe tweak it ourself.

Vanilla does not have chariot entries (the unit causing the problem) and we have another chariot unit that does not cause the problem...

Anyone else had this?

Just FYI.
