I am not too sure how security nodes work as I thought they just took the place of a chest or another interactable but I have not been able to find a single security node in any stage 3 level and I only recently learned that they spawn on stage 4 as well but I honestly doubt that they would spawn there either as I am not too sure they would only spawn on stage 4 and not stage 3. Also this is unrelated but I really wish there was an artifact gate on procedurally generated stage 5 maps, maybe I just missed it but I partially feel like there should be a new collection of procedurally generated stages just for stage 5 so placing a artifact gate somewhere around the map won't be so confusing as they're always on the same place in the regular stage 5 maps.
