@Nixal I don't think the fixes will work on 0.81, but they might. Don't count on it. What I do think is that you should upgrade to 0.81a. Note that you'll have to start a new campaign. As for your other question, when you do not enable the script, it is, well, disabled. It has no effect at all.

@Martinus That's odd, a lot of people have had it work for them... I don't know anywhere else the files are hosted.
