this happens to me. i'll just turn off the ds then restart chaining again. there was one time i screamed again, i was chaining a shuckle, when i reached 40 i saw one, carefull nature, yaey... then i put my synchronizer at top of the party, but forgot its only level one, i walked then comes a beautifly, man i was shouting as hell, its hard to chain shuckle sdo its a bummer to break a good 41 chainBy me, it's the chaining too. First the chain is going great but always
when I am around the 30 chains, some common Pokémon like Bidoof or Starly(Staravia) appears and breaks my chain,
and almost always I'm pissed off after that and i turn off my DS :P.
Yeah, well I don't scream at my DS but I am sure getting irritated about that stupid Pokémon that show up breaking my chain :PI guess I'm just don't get into games that much. Don't get me wrong, I enjoy my Platinum but if something goes wrong, I simply aknowledge it and move on. I've never screamed or shouted at a game because it's simpley "a game". There's no point in doing that since there's really nothing to achieve.
on diamond i beat the elite four and then ran out of batteries i went ape $hit on my ds!
