I have seen a few addresses values change to "???".
Does this mean that address no longer contains a value?

If this is the case is there any way to search for an address that has changed to "???" ?

I ask because I am trying to track down an address. When I leave the screen and enter another area a lot of the addresses turn to "???". I am assuming that this means that the addresses have lost their values. If this is the case then it means I can quickly cut the large list of values down by a large amount.

No not quite. They didn't "lose their value" but rather they have been deallocated. They are taken out of memory! Either they were reallocated somewhere else, or if they aren't needed at that moment just taken out only to be put back into memory when they are needed again...

You need to either find the code that modifies your addresses and do a code injection, or find a pointer using the pointer scanner.

When you change screen or whatever are those addresses no longer relevant? Or did they just move? If they are still relevant, find them again and they'll be somewhere else
