Whenever I make a scenario for 1.29f using the CivEdit program, it jams. I can add new units just fine and the scenario will play like a charm, but if I do things like changing map size, editing unit properties, or the like, after a while the game reaches a point (always random, sometimes its real early, sometimes real late) where it will jam and not go any further. Ive reloaded and that didnt work. Ive gone back 20 turns via save games and it still jams. Any ideas?

Huh, strange, you sure you have the Units right? does it give an error before crashing? Certain things will mess it up, although, Changing world size isnt one of them. Its kinda hard to believe, so once more, are you sure these are random crashes? Did it do this with the other patches?
