Before I slap down a million of these... Anyone see any huge errors?

The goal here was a 2.1 direct insert build that could keep a legendary silo firing continuously.

You have to have the buffer chests due to minimal loading time for the rocket (needs a buffer).

Added heating towers just for convenience.

What dumb mistake did I miss that I'll only notice after slapping down 200 of these?

(64 bottles/sec so it's about 15% overbuilt you can delete a few beacons if you want, but I couldn't figure out a way to get to 3 plants per silo)
