I'm getting this on startup:
Error while running setup for entity prototype "rfp-pipe-elbow" (storage-tank): next_upgrade target (storage-tank-2) must have the same bounding box.

Complex modpack with AngelBobClown, APM and a few others including flow control (maybe the new patch trying to be compatible with this is the culprit?)

Should be fixed in 1.2.7, can you check?

Wow, that was a quick fix. Seems to work ... now I only have to get that far in my game (recently out of steam age ... ;)
