Random disconnections and all quests wiped

[lennip]

Hi,
since this morning I have been randomly disconnected every few minutes when playing with my Marauder (name Mutty, rank 36, currently in Praag). I never had any big crashes or technical problems in RoR before. Yesterday evening I played with my mara for several hours until about 12PM (Western European time zone) and everything was fine...
Today I tried to log in with him again and got the infamous "The server has closed your connection. You have been disconnected" error message right at the start. I clicked Play again and was able to log in normally. But since that moment I am experiencing random disconnections every few minutes: I log in, start to play and get kicked by the server with the same error message. I waited a few hours to see if the problem disappeared, but no luck...
What's more, I noticed all my quests were wiped. Not only the dozen or so uncompleted ones from my ToK list, but also the ones I completed long ago (I go back to previous chapters and all the quests I already did are available again). Other achievements like unlocks and PQ Inf are still there so I don't really mind, but I wonder if doing again the same quests that I already completed before might mess with the DB or something...
What should I do? Do I need to contact a GM ingame?
Thanks for your help!

This happened to me too twice on my chosen, also quest were not also wiped but "resetted" mean im able to repeat all quest ever completed; even epic quest and get other rewards as well tough i didn't done that; i suspect some quest (new meddalions ones) had to do with it, but i cant replicate it in anyway.

Yeah I said wiped but you're right, it's more like all the quests have been reset as if I had never done them. Anyway, glad to know I'm not the only one it happened to
As for the server disconnections problem, I just cleaned the computer, uninstalled and reinstalled the game client, and it seems to have stopped... I still have no idea what could have happened between yesterday evening and this morning, since I barely used the PC in between, but anyways, looks like it's been resolved for now...
