Fallout 2 bugs

Quest-specific bugs
If you accept the Rescue Chrissy quest at The Squat, and kill Zeke but don't actually rescue Chrissy, and then go to Vault 13, Dalia is there and she acts like the quest has been completed.

Location-specific bugs
When viewing the town map of San Francisco, if you press 5, you travel to an unused area- it is a small black rectangle. The hexes there are plainly visible, and have 'unused art' written on them. Moving the cursor moves it but still shows the previous location, and this happens as well with moving the player.

Similarly, when at the Den, pressing 3 in the town map moves you to the cut area, the Den Residential. Moving the player character to the green exit grid moves him to the Den East Side, and the previously green exit grid turns red, meaning that is the exit to the Den entirely.

If you want to go to the Vertibird crashing place from Klamath your game crashes. Simply go into the options and change the brutality to the lowest.

Crashing and freezing

 * Occasionally, upon attempting to skip the Interplay intro, you will freeze.
 * Recruiting Dogmeat at the Café of Broken Dreams by feeding him some iguana bits instead of just showing him the vault jumpsuit (he recognizes it and joins you), the game may crash. If it does not, it lags excessively, and just exiting to desktop and restarting the game will stop it from happening again and you can pick up right where you left off at the cafe.
 * Sometimes specific save spots seem to get corrupted and, after loading, will display an error message and crash the game.
 * Trying to talk to Tandi about Frank Carlson will freeze the game.
