I don't know that anyone has a clue as to why there would be problems or ctd's when units sally. It makes no sense to us. I'm tempted to say it's got to be an RTW bug, but I really don't know. We don't think we have messed with anything that should cause problems with that element. If anyone has the slightest idea, please let us know. Thankfully, as you said, this is very very rare.
