Error core 90k, followed by error code 5003 (October 15, 2013, 5:20pm Eastern)

[Kimikryo]

Since enough people have submitted detailed reports, here is some additional information:
- it seems to happen in a timespan of about 3.5-4hours
- it doesn't matter if you are active or not at that time,
- nor what you are doing
- nor where you are

It's like your session simply expires. Maybe someone forgot to code in a check whether the player is active or not?

this really seems to be true I had my last 90k 5003 at 21:07 logged back in at 21:30 and now I had again a 90k 5003 and its 00:30 <_<
