Locutus has made a new version of his unofficial 1.04 Fallout 2 patch (made using the mapper). Here are some of the huuuge list of fixes:

• 
  - Fixed a bug that enabled you to go thru certain walls in Hubologist's Base and Cat's Paw
  - Now you're unable to get the loot from the four boxes in Broken Hills
  - Dead Enclave Guard from Klamath now has dog tags instead of the keycard
  - Holy Hand Grenade CAN be found now
  - Cafe of Broken Dreams no longer repops after being found
  - Now Vault 15 looks more like in FO1
  - Party Members now change thier appearance when wearing armor
  - Fixed a bug that prevented you from getting the best ending for Gecko
