Well, for what it's worth. Here's some results from my own little testing after slotting my new alpha boost and getting the mapserver disconnect slapped in my face countless times.
As already reported, slotting down and it worked fine, going back up to the new alpha and map disconnects were back again.
So I begun to test all my powers, this being on a Plant / Earth Dominator.
And it didn't take long to notice that everytime I casted Carrion Creepers, mapserver greeted me seconds afterwards.
Logging back in, cleared two spawns without creepers. Third, tossed CC again and boom, disconnected.
Tried again, same result.
Third time I slotted back down and casted CC. This time no disconnect and kept running the map with CC constantly out. Few minutes after that I decided to slotted back into my alpha (creepers still out mind you), and right away I got disconnected.
So yeah, it's in my experience definatly some powers that are the culprint behind it. Since as long as I don't use my Creepers, I can run missions without any issue. But as soon as the power is used, I'm off the server.
