Hello,
I have recently imported some Pokemon that I have caught in Let's Go Pikachu to PKHex and upon importing them I was greeted with the message "Invalid: Calculated CP does not match stored value", as if they weren't completely legal and legitimate (read: unaltered).
I stumbled upon this thread from a few years ago:
in which someone else seems to have had a similar problem and apparently, according to one of the replies (the one referencing another thread), there used to be a mismatch between the way the game itself calculates CP and the way PKHex does it, therefore no actual legality issue. However, there is a later reply in that respective second thread that announces a fix to that problem, so you can imagine my confusion when my unaltered Pokemon were flagged as illegal.
Given all this, I tried to generate a number of new Pokemon that were flagged as completely legal by the program, sent them to the game, levelled them up once and then sent them back to PKHex, which once again brought up the same legality error. Should I worry, then, if I want to upload those newly generated Pokemon to Home?
