Bots don't respect freshness/spoilage.
With one rocket silo for agricultural science you want to know:
a) when a ship rolls around to pick it up, only then do you want to load it using inserters with fresh first.
b) that same rocketsilo can do different things, too, like send up bioflux. But I like to ...

... obvious thing to do if you only have one silo is to enable automatic bot-based loading, in which case you don't need to know the contents since the bots handle all that
If you are only exporting one item, you could load it with inserters. In which case, again, you don't need to know the contents ...

... below the requested amount? And you save cargo bay landing slots by waiting until a full stack is needed before requesting any?

IMO, logistic robots avoid this problem because they have a built-in one-robot hysteresis. If a chest is short its minimum request 1 item, the bot will bring a full load ...

... could be repeated: it's possible a new item being just slowly added gets completely removed from the signals within the 2 ticks (reservation by bots is enough, it doesn't need to be physically picked up yet), so the stack size will also vanish, and so it will be compared to 0 again when some ...

... or other forms of energy):

Assembly machines, furnaces, drills, and their variants draw the same amount of power at all qualities.
Circuits and bots also do not draw more power at higher qualities.
Boilers/heating towers/etc draw more steam/heat/etc, but this is to keep up with their higher ...

... an item-request-proxy can point at non-existant indices. You can have a rocket silo look like this:

and bots will happily fill the exact slots, resizing the inventory as needed, allowing gaps in between. The api does not allow that, inventory.resize() doesn ...

For some reason, logistics and construction bots seem to have the wrong colours and are transparent.

This only started happening recently, they were fine until randomly they broke 10 minutes ago.

I am using a save with a lot of mods, unfortunately, so debugging it is hard ...

While that does make sense in some scenarios, could you make it work when it has more construction bots than its mobile roboports can manage? So the access robots should not be considered as part of the logistics network and instead be considered items?

You should limit with circuit conditions if you're using bots. Link up the assembler(s) making the centrifuges to the chest holding them and have the assembler turn off when the chest hits a certain number. Using circuits instead of the X means that if you ever take down a centrifuge with bots, they ...

I made a simple mod that prevents trains from switching to automatic mode. You can toggle it on or off at any time.

... but it should be much faster than chopping down trees by hand. Grenades are relatively quick to get too. And IMO, your proposed solution doesn't really match the style of Factorio.

You could also try a mod that adds something like construction bots early on, such as Nanobots: Early Bots 2.0 .

... Construction Approvals mod https://mods.factorio.com/mod/ConstructionPlannerContinued depends heavily on using force changes to allow or not allow bots to pick up jobs for placing ghosts.
But there's currently no event-driven way to detect when an entity has changed forces.
This results in a ...

What did you do?
delivered items to an assembler via construction bots, then changed my mind and placed removal orders, then changed recipe.

... intake belt to the ag towers and set them to harvest when the buffered fruit is below some level. That's more or less the same thing you do with bots to prevent overproduction.


It's also much more of a pain to setup belts on Glebas landscape IMHO. But I will admit, it's probably a very similar ...

... real factory.


The problem with belts is that it is easy to over- and underproduce.

Not really. It's trivial to wire your intake belt to the ag towers and set them to harvest when the buffered fruit is below some level. That's more or less the same thing you do with bots to prevent overproduction.

... more reasonable. There are achievements for hand-crafting as little as possible. For getting logistics requests. For placing more buildings with bots than by hand.

There are no achievements for hand-crafting, say, a rocket silo or some other end-game item. Indeed, you can't hand-craft quality ...

The personal robots in this save are broken in a couple ways. Note that the player's inventory is full, and if it is emptied they do sort themselves out.

STR:
1. Have armor with a personal roboport equipped
2. Have a full inventory
3. Damage something
4. Fill the stack of robots (or, replace with ...

... 2 before placing.

However however, if I had a ghost selected on purpose then I wouldn't want it to stop being a ghost cursor just because, say, bots delivered some to me.

Solution would have to keep track of the reason why you have a ghost cursor (i.e. remember that you only have ghost cursor ...

I guess I'm bad at searching the forum oops.
