At least that is all that I can think of.
The script - at least when looked at as "loaded or not loaded" - has no effect. I ran an 80 game test this weekend, and 70% of "first battles" CTD. On reload, half the time I'd start the script, the other half I just forgot. No difference. No CTD on the second time around.
