MapServer Disconnecting when entering missions

I've been having a problem, pretty sure since i17 went live and even more so now with i18 and GR being live where when entering certain missions, the missions will not load and after a couple minutes the mapserver will disconnect. Which missions are affected seems totally random, but seems to happen around 1 out of every 8 or 10 missions.

I've tried on multiple computers running totally different hardware and software and also it doesn't matter whether I'm on a computer that uses a wired or wireless connection.

I do not get mapserved like this anywhere else, not in zones, not when I actually make it into the missions, not anywhere. It does not matter whether I'm on a team, TF/SF, or if I'm solo, it will happen eventually.

I've tried computers that are freshly loaded and have nothing on them and I've also checked my firewall settings and all ports that need to be open for COH are open, and I'm using the same internet connection I've used since CoH launched.

Sometimes I can enter the mission after having been mapserved entering it the first time, but other times there have been missions that no matter how many times I try, I get mapserved every single time I try entering. I'm unable to get any netgraph info since this all happens at the loading screen when entering a mission. Once the mapserver has disconnected I have to totally exit the game otherwise I just get a blue cloud like screen and no login screen.

Has anyone else encountered this? Needless to say, it's been very frustrating and I hope a solution presents itself soon.

Yes i have been having a similar problem but it only seems to effect toons that have switched sides in my case.
When entering a new mission it sometimes fails to load and then disconnects, upon reconnection to coh i find the toon that i was on has jumped accross the map (in nerva he always ends up inside the building at the science trainer) so i cant see how its a problem at my end since i have never had this BUG before.
On another note there is also the MM pet bug which seems to put pets out of sync with the game upon leaving a ferry/train or entering an outside mission map. The pets are totally unresponsive and cannot be dismissed so therefore cannot be resummoned. This leaves you with either logging of for 20 mins and trying again or keep zoning as i have found this will eventually re-sync the pets. Teleporting them will not re-sync them either.
Its a bug which has stopped me playing my MM's as its a right pain in the *** when it happens
Both bugs have been reported to the powers that be so hopefully we will see a fix for them soon.

Small additional notes:

The problem seems to occur more often during peak server load hours, but it can occur at any time.

If I have a teammate with me with the same exact mission, only one mission so far at a time has been affected.
