Dimensions seem to lose their associations A LOT. Roll back your timeline, modify an assembly level driving sketch, redefine a feature that includes but does not change the attachment point in question and > BOOM ! < your drawing is now littered with un-associated dimensions and yellow flag warnings. The most annoying part is there are 2 attachment points to a dimension and you have a 50/50 chance of picking the the one you think has gone wonky.
Can we get the failed association flag place - AT - the attachment failure instead of generically on the dimension? Fixing problems is annoying but sometimes unavoidable. Just need more bread crumbs to help resolve the issue...
