Ivory Tower continues to have bugs, and these bugs make hunting there very annoying. These bugs consist in being hit by invisible or distant mobs, in not being able to use tele scrolls, escape scrolls, or -warp commands, in not being able to use stairs to go to lower or upper floors. Furthermore -fix and the restart and quit buttons do not work as a way to remedy the situation. Only force quitting enables one to return to game. This is a chronic ( though not ever-present ) bug lasting for years. Perhaps it is a carry over from NPC Soft. Fixing this would be most welcome.
These are bugs with the client and sprite animation rates. Not too much I can do about this.
Put scroll of teleportation on a hotkey, and use it on the 8th floor to fix the screen.
