To clarify, your saying that

i) You remember adding ways to the map at sometime in the past
ii) Those ways are no longer showing up on the rendered map
iii) When you view the raw data in an editor, you don't see lines for those 
ways either
iv) You aren't able to determine when or who deleted these ways.

If all of the above are true this sounds like either someone is deleting 
your data or there is some technical problem.  Do you remember when these 
ways were added and when you last saw the on the map?

You mention "Sometimes the way appears in a different zoom level...."  that 
confuses me a bit.  If the way shows up at any zoom level then it should 
show up as a raw line in an editor (and when you view the raw data)  that 
indicates a rendering problem (does forcing the tile to re-render with the 
interface at informationfreeway.org fix it?).  I've often seen the renders 
get some ways in an larger edit but not others (a re-render fixes it), but 
that doesn't sound like the problem your describing at Hillyard.
