Check that it is actually locked into the proper position for visual and has not started to slip.

It is highly unlikely to be due to movement of the mirror for collimation, as this only moves it a tiny amount (generally 1/10's of a millimetre at a time).
I agree with Gabby that most likely it is the seating of the collapsible tubes. Make sure they are fully extended when you set up, or if you leave it set up (especially in a vertical position) then check they haven't slipped down at the mirror box end: this would explain the need to put the extension tube in.
If you do leave it set up in future is is probably better to leave it in a horizontal position: this has the bonus of being less likely to get muck on the mirror too.
All the best,
Dean
