Hi, new poster here. I have a Shiny Typhlosion that I've carried from Heartgold all the way to Ultra Moon. I'm planning to transfer it to Violet soon, but PKHex has flagged it. I don't want to risk being banned from Home or Switch Online, so I thought I'd ask for any tips here. I've made modifications in the past, so that's probably what's getting flagged. Any tips on what I should be trying to fix? Generating new PIDs hasn't helped much.
