when having all angels mods and all yours, the bottle gas handling tech cannot be investigated, its placed below fluid handling 2, but when you investigate that one, the bottled one remains red
(The tech I talk about is the one that gives you the hability to fill a gas bottle with H2S)
It's probably best to poke Angel about this issue. He rearranges my tech tree a fair bit, and on my end it's accessible.
