Photoshop: Loss of other history states after taking snapshot and making a change on it

In PS when I take a snapshot of a state and, by mistake, make a change to that new snapshot I can not go back to all the states of previous work. They are lost. Why can't I go back and continue to work on all the work before I took that snapshot?

It would be good to preserve all previous work and be able to go back to the work before the snapshot somehow. The history is all lost.

It sounds like you need to spend some time reading up on how history states work.

By default, if you go back in history and make more changes, you lose the changes after that (because you went back).

You can turn on non-linear history to keep the other states, but you can't mix things you've done and undone (well, except using the history brush).

There is no history to go back to. I just make a change in the new snapshop and the history is erased. This should not happen and I don't need to reread the manual I am aware of how it works. Non-linear history is very awkward.

It sounds like you really don't understand history states, or you wouldn't be asking a question about the behavior.

After going back to the snapshot and making a change, you branched your history on the document -- the other history states no longer apply, because they are no longer part of the history of your document. If you undo your change, you get your history back, because you've no longer branched your document history.

Yes, non-linear history can be awkward if you don't understand what it is doing. It can also be very powerful if you do understand it.

I am suggesting a CHANGE, not trying to figure out the problem I have. I already know how the current system works as I am accurately describing what happens sometimes when I am not careful and ACCIDENTALLY make a change on a history state when I am comparing two snapshots.

There could be a new history ( this is a suggestion for Adobe) series started for the new snapshot or a warning that the old history states would be erased if any change was made on the snapshot.

It's already there with non-linear history.
Otherwise, the change doesn't make sense.

Chris,
You can sometimes be very helpful. In this case I don't think so. I think a warning would be helpful so I don't lose my work when comparing two snapshots and accidentally making an adjustment. (non-linear is not very useful to me as a regular function) You don't agree. Let's just ignore me, the customer, and keep things the way you like them.
