Effect engine chase

I have a show that I've been running since the beginning of October. For one cue in our show we have a desk channel chase. The chase was built with the effects engine and steps from fixture 1 thru 10 in that order.

Two days ago the chase got screwy, and instead of starting at fixture 1, started at fixture 6. We have not updated for changed anything in that cue since we started our tour.

We are running our show on a Ipc, and the software in one release behind (last install was a full image install). The show is run off one cuelist (approx 495 cues).

Has anyone seen this before, or have a fix of some sort?

Thanks for your help,

Justin Dowbiggin
