I do not use probes and this is one of the reasons; I do not like positive numbers for the tool offset and I never use them.
When you have a positive number and accidentally erase it the tool goes too far down; with a negative number the tool stays too high, I prefer too high.
I have no idea how you can guard against it happening in the future as long as you use positive tool offsets.
