not sure how this one is occurring, but i cannot get sufficient resources to my window installer.
In the attached you will note I have 3 window producing slots, all of which are loaded completely (excepting the one that just sent off some windows), which lead to a stockpile which requests 12 windows to be delivered to it.
This then goes to the installer, which should be requesting 5 windows every 142 seconds.
Each of the manufacturers takes 54 seconds which gives approx 7.8 windows produced every 142 seconds. - fitting with the view of full stockpiles.
Having said that, the installer robots are claiming insufficient resources 50% of the time and are the principle bottleneck in my factory.
I initially noticed it with electric window installers, and pulled back to manual for the simpler version -which didnt actually fix the problem.
I did note that the problem seems to go away if not running at full speed.
i’ve taken a save copy if it helps.
