Buffer chests only report their net requests to the circuit network.

[Battle Pigeon]

Bug: If a Buffer chest requests an item, it will only report it's net requests to the network.

This can cause an issue where all requests are reported to the circuit network as satisfied, but the the buffer chest is only half full.

Steps to replicate
1. Create an isolated logistic network with no logistic robots.
2. Add a single buffer chest.
3. Set the request for any count R of items. (Easiest to replicate with a single stack request)
4. Put any number P less than R items in the chest. (Easiest to replicate with a half stack of items)
5. Read the requests from the circuit network.

Expected:
R = Total requests from buffer chest
P = Provisions from buffer chest.
The read requests will be R-P

Actual:
The read requests will be ((R-P)-P) or 0, whichever number is more positive.

Example 1

1. Request 100 rails in a buffer chest
2. Add 50 rails to the buffer chest

Expected:

100-50 = 50 remaining rails required to fulfill the request

Actual:

100-50-50 = 0 remaining rails required to fulfill the request.

Example 2

1. Request 100 rails in a buffer chest
2. Add 25 rails to the buffer chest

Expected:

100-25 = 75 remaining rails required to fulfill the request

Actual:

(100-25) -25 =50 remaining rails required to fulfill the request.
