Unexpected Meridian Flips

[Shibby]

Recently, I've found that when I try to slew to a target near the meridian, my mount is flipping when it shouldn't (i.e. to the wrong side). For example, if my pier-side is West, pointing East and I try to slew to a target that's East of the meridian but within a few degrees of it, the mount tries to flip. My mount is a Mach1GTO and I'm using ASCOM.

This is a recent problem - I don't think I've changed any settings, but I'm not sure where to look - any ideas?

Just a follow up - I think this must have been down to a timezone thing. Even though, the mount time seemed to match up as far as I could tell, re-synching from PC seems to have solved the issue (before the clocks changed, this was). Or that could be a coincidence! 🤷‍♂️
