So I have to go into the dark cave to save some boy. I go to the cave and attempt to enter. First time game crashes. The second time and from there onwards I can enter the cave but the screen stays fixed on the overworld and it knows I'm in the cave as my minimap changes to the cave. i can move the camera around using the L Shift key and I can cast spells but I cannot see the inside of the cave. Any ideas on a fix?

Do you have Caps Lock enabled? Probably not if you are using the Shift key to move the screen focus, but if it is, disable it. Enabling Caps Lock, or holding down the Shift key, lets you move the screen focus away from your character (to see or toss stuff further), but can result in the screen not following when entering hatches/caves or using ladders/stairs.

If you save inside the cave (under a new name) and reload, does that get the camera focus back on your character?

Oddly enough when I loaded the game just now it worked and i have no idea why. Thanks though,
