I made a quick look at SkyLine and discovered that quite a lot of trainers are corrupt. A fix will be available soon, when I get home after work, that is.
I am so so sorry if it took my a while to realize this bug's game breaking. =(
Onto other topics...
Angeallen won't be showing in SkyLine though, nor any custom-made, 4th, 5th nor 6th generation POKéMON. I'll be sticking with the 1st, 2nd and 3rd generation of POKéMON.
But maybe I'll add Angeallen, and a few others, if I feel like it =P
