- Line tool bug. If you select the line tool and then change the Focus of the cave, such that the screen has moved horizontally, you lose your ability to place items. So always disarm the line tool when scrolling the cave!
- Random command bug. Sometimes your joystick movements seem to trigger a random menu command. Perhaps the colour menu will appear, maybe it'll be the cave parameters, or if you're really lucky (!) it'll be the dice feature, randomly spraying your delicately crafted puzzle with whatever element you're working with.
- Save/load bug - Sometimes the kit crashes after loading or saving a cave. Usually, the cave will be saved to the disk OK, though very occasionally it screws that up. That's why I store my caves as snapshots whilst developing them.
- Intermission bug. If you load or create a new intermission, the Focus command is disabled. This is fine if focus is on the top left of the cave, but if it isn't, you're pretty much buggered
That's all that comes to mind... Do you know of any others to be aware of?
