Iv's reroll missing

[Raiak]

About 20 minutes ago I had a problem with an ivs reroll, a friend gave me two reroll because I was not going to use them, one from ivs and one from natu, the one from natu I used in my zapdos to change it from releaxed to bold and the of ivs I was supposed to use it in mew, it happens that I spoke with the npc and I just had to give him accept to change his ivs and wrote some messages in the guild chat, without realizing it apparently I had a connection problem but I gave him accept without knowing about this problem and I did not realize it because I had no player nearby so I did not see them disappear, I gave him accept and nothing happened, immediately afterwards he takes me to the home screen and I enter again, I noticed the mew and their ivs were absolutely the same and the reroll is no longer in my bag

 

 

Sorry if there are many errors or some things are not understood, my English is not very good and I used the translator
