My girlfriend, (SerahLewis IGN, silver server) is having a bug that the first pokémon in her party keep being replaced by another one

the first time her poliwag as turned into a bulbasaur lv10, the second time her budew turned into a bulbasaur lv10, third time her ponyta was turned into a budew lv24, fourth time duduo turned into a budew lv24 and fifth budew lv16 male turned into a budew lv25 female

 

the first time just with a relog the poliwag was back, but when occurs more times, was more hard to back to normal, hope someone can fix this bug, or she will stop playng this amazing game ;^;

 

prints are from when duduo was replaced by budew lv24 then he back

 

always occurs to the first pokemon in party

 

Im having the exact same problem. Just logged on amd my lvl 22 pikachu turned into a lvl 5 charmander. Really bummed cause pikachu is my fave pokemon......if you find a resolution please let me know
