Yeah I suppose it's possible that someone else logged into the D2 account since everyone who runs a series in that lounge has access to the D2 account.
Also, my main account is indeed attached to those side PS3's, as are the other SNAIL_DivisionX accounts. Unfortunately, it's not feasible for me to only have one account on each PS3 because I'm constantly logging on to all five SNAIL divisional accounts to add and delete drivers. Hopefully that's not the issue though, because if it is, that's no bueno for me.
Hmm that's something to consider, but that still would require me to power up multiple PS3 if I'm just doing something simple like adding new drivers to their newly assigned division (when I'm adding more than one at a time - which happens quite often).
Sorry, I can't resist that damn TOTPP urges!
