Okay, this thread is kinda' both a bug report and a suggestion, but I wasn't sure exactly where to put it, so I hope this is the right section. OnO
So first of all, I had placed a nickname on my RainbowPonyta, and then I loaned it to someone for training. I got it back:

But the nickname was removed:

This is not the first time that this has happened.
And I know people cannot remove nicknames from loaned Pokemon, because, just to see if you could, I tried it on a Pokemon I loaned from my storage.
So I was thinking, can there be something where the nickname stays on the Pokemon even after it's loaned and comes back? Sorry if I sound lazy, but it's just kinda' annoying having to re-nickname everything because loaning it somehow strips the name off when it returns. If it's a bug, then I hope it gets fixed.
