I've been chaining on Route 16 for a Shiny Phantump for awhile now. But, randomly, whenever I get like 20-25 in, when I press Y to activate the Poke Radar it'll make the sound but nothing will happen - it doesn't say "Your battery is at 45, please walk around some more to use the Poke Radar" or whatever, there's just no dialogue box at all . Then I press it again, it says my battery is at 0 and my chain is broken. This has happened like 5 times and it's really pissing me off. I'm not heading into any bushes, using the rollerskates, going into my bag, walking outside the field or anything. I'm just walking around in the flower, recharging my Radar and it just breaks itself. Is this a bug or something?
