About a week ago, I found this when going through a random seed in 1.12.2 and got pretty damn lucky. Any idea what the %/odds are for 2 fortresses generating right next to each other in the nether?

Happens more often than you think.

Having one fortress is all a speedrunner needs though, unless the blaze spawners of both fortresses are next to each other.

Interesting.

benex got 3 fortresses next to each other on stream and nicetwice got 2 fortresses 2 bastions and a ruined portal.

that’s also 1.12. pretty common compared to more recent versions

I just got 3 next to eachother in 1.14.4 today, I could find it in a vod maybe

I've had a lot of double fortress for the low amount of time that i've spent generating seeds and i couldn't complete any of them because of pearl trades
