Schwertz: FO1:

- Each time you talk with potential enemies of the Vault decreases a counter for Vault discovery by the said enemies by one day. So limit those interactions to the necessary minimum. (It's a spoiler of course but you can not get this knowledge neither in-game nor from manual nor even from the most of the fan-made resources. Found this fact when decompiled scripts myself.)
- Arranging water delivery with caravans postpones Vault demise form the thirst but discovery counter is decreased for the fair amount too.

Jigby: I thought that the patched F1 doesn't have vault discovery. Didn't they remove it in the official patch?

osm: Yeah. Children were ofcourse censored out of euro versions for ages, whitewashed pics is a later "addition".
