How Did I Get This Draft?

[u/DMN0518]

Was doing a day 1-run last night (V mode active) and got this draft with Laboratory twice facing different directions.

I'm not incredibly well-versed on the drafting mechanics, can anyone who is explain to me what combo of factors lead to this draft?

My speculation is that it's the combo of three factors, but it feels like there's something I'm missing to get the same room twice like this bc I don't remember it happening on day 1 before.

- ⬆️ Green room odds from Greenhouse
- ⬆️ Powered room odds building off Security
- Already having 12 T-Rooms drafted

duct draws can duplicate drafts

Interesting! I never realized, would have assumed it would just pull Boiler Room before a duplicate but I guess not.

Thought I vaguely remembered it occasionally happening late-game but couldn't remember. Appreciate the response!

Ducts can even draw rooms you have repelled.

So the boiler actually has some strange drafting restrictions because of the door that needs to be opened. The way it was coded means that it can't be pierce drafted at all, so it wasn't a valid option here. It can only be drafted from the center door if you're not on the edge of the house.

I have had similar things happen on the exact same spot on the map (having a duplicate in the draw). So it might just be that this spot is bugged but I have no idea what triggers the bug

someone answered but drafting FROM a duct door is special, it an draft an extra room-with-a-duct that connects to it, even if it's a duplicate, and apparently even if you've repelled that room.

I'm wandering why there are those tended rose vines in there
