[2.0.12] Roboport network requests increase for one tick on bot assignment

[syvkal]

How to reproduce:

• Setup two roboports, one reading network contents, and one reading network requests
• Link them to a pole, one red, one green, so you can read both outputs
• Setup a requester chest with a request for 50 of an item (something not a multiple of the robot cargo size, I was using a size of 4)
• Place a storage chest and place 50 of that item inside
• Manually step through the frames one by one
• The network requests are instantly satisfied by the storage chest (this is incredibly useful for my use case)
• As the bots get assigned to pick up items, eventually the network contents goes negative (not a bug) since 50 is not a multiple of 4
• As the last bot gets assigned, for a single tick, the network requests increase before correcting itself the next tick

While I understand the network contents are designed to go negative, I believe the increase in network requests for a single tick is a bug.

Revisiting this post because I noticed that with enough bots in your network, this issue does not occur.
While I might be missing some underlying logic, I still believe this to be a bug.

New steps to reliably reproduce the issue:

• Setup two roboports, one reading network contents, and one reading network requests
• Link them to a pole, one red, one green, so you can read both outputs
• Add 5 logistics bots to the network
• Setup a requester chest with a request for 50 of an item (and robot cargo size of 4)
• Place a storage chest and place 50 of that item inside
• Manually step through the frames one by one
• When the network contents goes negative, for a single tick, the network requests increase before correcting itself the next tick

When using more bots (for example 50), this single tick increase does not occur.
Additionally, when using only 1 bot, this increase happens mid-transit - likely when the remainder of the bot's queued tasks are assigned.
