Linear Pattern Problem

I've run into a problem with linear patterns in assembly.
I make wire baskets. I create 2 perpendicular wires and patternthem out along an axis created by the intersect of 2 planes.
For different sizes I make configurations of the pattern.
Occasionally I will run into a a pattern that does not update orchanges MID-PATTERN!.
I don't know when it happens or what might be triggering it!
The fix is, I suppress and then unsuppressed and the patternreturns to it's correct orientation.
Has anyone else run into this?
I'm running 07 sp2.2SolidworksAssemblies
