T4 quests have the house_tudor_01 which I call the library house. (kinda like the cathedral)
Forges are easy with just 1 point, workstations need 4 pts in INT. umm.. not yet.
I check every workbench I see (all stations actually). A lot of POI have a workbench in the garage.
Bash in a panel and peek. If there is one, bash panel 2 loot. (check for zeds first d'oh!)
RNG is sometimes nice, sometimes not. By the time I got the cement mixer schematic,
I had almost 12k cement waiting, just from looting POI.
This time, I have lots of acid (and wheels), first playthrough, day 20, total of 6 acid (on 200% loot that time too)
Was on 200% loot until day 10, 100% now (day 20), even after dropping it back, I've found 6 more acid.
(and another 2 dozen eggs. main reason I do 200% early, is for food. Books when MP to share them)
First play through, got the purified water book in the first couple of days.
This time, no go, but got the can dance on landmines. (love that one)
RNG likes to tease.
