With the new flame turret being a 2x3 structure we really need the blueprint export/import to save the orientation of the buildings. I had a monster of a fire-base blueprint become useless because it attempted to place the flame turrets in a vertical aligned position & overlapping stuff around them.

Can you give me the blueprint that doesn't work?

So im having the same issue and i believe the problem is that you forgot to properly code non-square buildings because it only fails on splitters and accumulators for me. both are 1x2.

Incase you ask, http://factorioblueprints.com/view/psLXd7YmW9Fed8J3E, this blueprint does not work properly. Nor do nearly any splitters.
