Error when changing slider value of Edonia's Ego Maximum Power Charges Mod

[Blitz54]

For some mods that go between a negative value and a positive, we get an error when going from positive to 0. Adonia's Ego with {range:0.5}+(-1-1) to Maximum Power Charges is the easiest way to test. Changing the numbers to -5-5 still bugs, but higher values like -50-50 there is no error when landing on 0. It's something in itemLib.applyRange. Replacing that func with the one in PoB1 removes the error. But of course we need the new code for corrupted mod scalability.
