When I was ingame, I DID notice a few glitches/bugs.
First, if you have too many 99's, and try talking to the Wise Old Man, your account freezes and you need to close your client and reopen it to log back in.
Second, the dragons are glitched out. If you go to Brimhaven Dungeon or to KBD, under them, there is a tile with a skull.
Lastly, the slayer tower monsters. All except the Abbysal Demon and Dark Beast are glitched, when they attack.
Please fix these soon.
Thanks.~
