It's possible to make everyone in the game freeze/crash by copying a large page of text and pasting it several times in world chat. - You need to limit the characters in the chat entry box to prevent terrorism of this kind.

Character: Belgarion

Mission: Desert Multi

Bug Report: Couldn't fight the boss, but could watch the other players fight it (screen still in cut scene sizing for the whole fight) and got rewards when they won.

Character: Elharith

Mission: Battle Arena

Bug Report: Today, there were a couple times this afternoon where the arena froze right at the end of battle. Luckily, it had ended soon enough that I got the win, but I wasn't sure if I got the reward because I had to refresh in order to get out of the screen. It happened twice in a row over about an hour of time, but seems to have resolved itself. Another player reported in chat she had a similar issue about the same time I did, and was asking if anyone else had had it. I initially thought it was my computer being squirrelly, but figured I should post a bug since she had the same kind of problem.

Character: Alyniana

Bug Report:

Guild mass mail-out threw an error code ID 517 and disconnected me. Before it disconnected me, said it was sending mail, but it didn't. (Also, I've noticed all the cool downs say 8000, and you don't know how long it is until you actually build.)

Character: Ignatius

Mission: Survive the Raider Ambush

Bug Report: Fought the battle for the chest, but couldn't open it. Got froze in cut scene view, even though I'd already killed the bandits who'd popped out. Had to refresh to open chest.

Character: Lenne
Mission: Desert MP
Bug: Last battle, I could not enter it after scene. I refreshed, and my team lost. Once I was back in we could not start battle a second time. After a second refresh, we were kicked back to town.
