Shiny pokemon generation seems to work for a while. After writing them to a save a couple times (I haven't kept track of how many times a given pkm can be imported to a save file before this happens), they're no longer shiny and I need to 'reset' them. Is this an actual bug or am I doing something wrong?
Here are the two I most recently tried to import to SS; they came over as shinies in Black no problem.
So you're saying that the problem apparently occurs if the Pokemon are put into a(n) HG/SS save file and that save file is loaded/saved a few times with no modifications whatsoever? That's very, very hard to believe with the current design. If you can find a way to reproduce the problem, and provide the steps you took to do so, I'll look into it.
Well, the Ditto was my fault (didn't use the PID finder for a shiny); for the Umbreon the PID is the same as when I originally created it, but the Shiny box is not checked and grayed out. When I use the PID Finder to re-find it, the Shiny box is not checked but filled in completely (clearing and re-checking the box works).
...hard to explain, although there's probably a user error in there someplace. I'll try sending it over via ShinyGTS and see if that sticks.
