While playing Kanna on my desktop I disconnected every 10 minutes or so, sometimes disconnecting immediately upon logging in, and every time with an application error:
I switched to playing Kanna on my laptop and using my Bishop as a HS mule on the desktop, and while partied with the Kanna I still disconnected just as often with the same error. Hiding my Bishop in the Cash Shop and only coming out to HS seemed safe, but I still did occasionally disconnect in the ~10 seconds I was out of the CS.
Since I finished Kanna (and finished being in a party with Kanna) I've not disconnected at all, I afk'd in a LHC map with my friend who was training his Kanna and didn't disconnect, did an empress run and a few party quests and didn't get the error at all. I didn't reinstall or reboot.
edit: spoke too soon I guess, just got this error trying to enter Magnus (normal):
