You didn't mess up as long as you didn't go over your target frame.
Roamers might advance your frames or there is a moving NPC in that area that could do it :)
okay im on frame 12 and my target is 15.. Do i need to get on frame 14, then exit the pokegear, and pick up the egg asap? When i pick up the egg it will move it to frame 15 and give me my flawless IV's correct?? Im nervous.. lol this is my first egg RNG, i finally got RNG reporter to work last night thanks to your help :)
