Attempting to buy a Meow Pets guide book from Corporal Wilson at the Orbis Park will result in an instant dc to main menu. How to reproduce: Go to Orbis, Orbis Park. Talk to Corporal Wilson. Attempt buying one (1) pet Pet Command Guide: Meow pets. (This is near the very bottom of the scrollbar) Game with disconnect and go back to the log-in screen. I don't know if other stores that sell pet books will also cause this to happen, but it seems likely to me since its the item that seems to be the problem.
I was able to reproduce this error only for the NPC Corporal Wilson in Orbis. You should be able to purchase command guides with no issue from Doofus in Henesys or Patricia in Ludibrium. Thanks for the report, hopefully we can fix this soon.
