Object Snap is 'slipping'

I don't know what I changed, but suddenly when copying or moving sections already drawn, with Ortho on, when I release from my move, the entire selection has shifted.

This is quite frustrating, and never happened before.

I take these to a point on a line that seems to highlight or 'accept' that location ~ when I click and enter, it's on the same axis, but NOT where I intended.

Unfortunately, I do not know what the 'problem free' settings were, but I currently have the following activated in OSNAP:

Endpoint

Midpoint

Node

Intersection

Nearest

Any assistance would be appreciated, thanks.

Could it be that some of your geometry has a "Z" greater than 0.00? You might want to check one or more of the lines to see if that is the case.

when I release from my move.....

Just to be sure, are "Clicking" to select a basepoint on your selection, and then "clicking" on a destination point, or are you "dragging" the selection to the destination point?

As a test, turn off Otracking, Osnap, Snap. Now start your move command, pick the objects, pick your base point by typing ENDP, pick the endpoint, now type ENDP (or perp, INTersection, etc.) and pick the second point. Does that work where it didn't before?
