One possible source of it is switching computers. Which tutorial tips you have already been given on a character is stored on your local computer, not on the central server. If you play a character that is high level, and then switch to a different computer and play the same character, you can trigger all the old tutorial tips that you'd already gone through another time.
The gaining a level tips are the most obnoxious ones. It doesn't just give the tip when you hit the target level. It gives the tip when you level and are at least the target level, if it hasn't given you the tip on that computer before. That means that if a player with a high level character switches to a different computer, the first time he levels, the far right area of his screen gets flooded with tutorial tips.
People posted videos of glitches on youtube and some showed: going threw a wall, getting yourself trapped(not on youtube), even hitting your own teammate in a battle, and moving around in a battle(facing different directions while in battle:backwards, forwards, left, and right. It's really weird. Seriously. This bug isn't supposed to be in this game and i thought it already been squashed! Killed! Gone! But yet it isn't. Its like it crawled back in the house to make things worse again. Or maybe its the graphics but I most likely dont think that.
Merle Summoning Players without Reason: Sometimes Merle likes to check in with his students, however we've noticed lately that he's been calling on our young Wizards every time they gain a new level. Don't worry, he may not always have a quest for you, however it's a good reminder to visit him, as well as your Professors, on a regular basis.
That has happened to me a lot of times it just means that your computer is loading that place and you have to wait until that circle goes away and then you can go to that place.And when ambrose pops up he is just giving you a tip he does not want to see you.
Does anyone remember what you did immediately before this circle popped up?
Yes Yes Yes i do i had finished a quest in mooshu then i was walknig to go help a friend then all of a sudden headmaster ambrose popped up he I have some thing speical ready for you.Then when i went he said Keep srearching young wizard we need to know all about malistaire's plans! ! !
i had that happen to me just recently, i was in marleybone and i had just become a level 30 wizard and the headmasters circle popped up on the screen and he asked for me to come to his office immediately and when i got there he had nothing to say to me, not even an exclamation mark above his head, i just want to know now, was it actually a glitch or not?
