I have 4 reactors on my mining ship. The first (primary reactor) pulls uranium just fine. It's name:
"Large Reactor (Miner 1: Control) [Ingot/Uranium:P1]"
so does the second and this is it's name:
"Emergency Reactor (Miner 1: Storage 1) [Ingot/Uranium:P1]"

The reactor in the next section named:
"Emergency Reactor (Miner 1: Storage 2) [Ingot/Uranium:P1]"
Does NOT pull uranium; not does the final reactor:
"Emergency Reactor (Miner 1: Engines) [Ingot/Uranium:P1]"

I can manually move uranium into them (and I mean through the network) and the "Use Conveyor System" option also works.

There are no errors in "SpaceEngineers.log".
In "InventorySort.log" I can see entries for the first two reactors but not the last two.

All of the connectors are configured the same and locked. All of the reactors are configured the same. (Off, and not to use the conveyor network.)

Wild theory #1: Is there a depth limit to the number of network it will look through? The last two reactors are 4/5 networks away.

Here's[s28.postimg.org] an edited screenshot showing the layour of the connectors & reactors.

Unrelated question #1: As much as I love this mod it noticeably slows down the game (older processor). Is there some way to configure the update frequency? Once every 30 secs should be more than enough to work without major slowdowns.

PS: Although labled "Emergency Reactor" they're just small reactors.
