I went to catch Kyurem, and my party was full. I used a Masterball as soon as i encountered it (level 50 one) , it said "kyurem escape , your box is full" something like that. i dont know what the problem was , i even threw my ultra balls but same thing prompted , even my master ball got consumed.
Can i know what the issue is? or can you explain what should i do now? because im really stuck now.
