Ruffy, try the following thing.
- Search the pokes that have the description "you see a broom, Blastoise bla bla bla".
- Pick 1 pokemon (use a magikarp from the groun, no risk with those x'D), and 5 poke-brooms, go to nurse joy and heal them.
- Repeat the process until you fix all ur pokes.
Keep in mind, that the "bug origin" is the hatched egg, so don't try to "fix" that pokemon/egg, otherwise, everything will be turned into brooms again.
Still, you'll need the help of an admin to recover the "Egg", because I never find a way to "fix it" manually.
This was the faster way to solve that problem, I hope it stills working.
Warm Regards,
