Symptoms:
Construction bot when upgrading a pipe. The bot will return a full stack of old pipe.

Step:
Since this mod useless in vanilla I testing this bug with Bob Logistics and Nullius
1. Place 1 Iron Pipe with in construction network
2. Make upgrade planner, upgrade from Iron Pipe to Stone Pipe
(In Nullius skip this step since you can upgrade from Pipe1 to Pipe2)
3. Upgrade the placed pipe via upgrade planner
4. Wait for bot do their job
5. The bot will return with full stack of Iron Pipe

Mod Lists:
- No Pipe Touching
- Bob Logistics
- Bob Lib

I found some quick fix for this
put this
event.robot.get_inventory(defines.inventory.robot_cargo).clear()
event.robot.get_inventory(defines.inventory.robot_cargo).insert({name = pipeType})
in "control.lua" on event "defines.events.on_robot_mined_entity" before "-- update adjacent pipes"

Thanks for the report, i just got back from a break. Ill check it out this evening
