In Krastorio 2 it has a second tier of beacons called Singularity beacon.
It accepts 2 modules, but its effect transmission efficiency is 0.75 and not 0.5, so the calculator shows lower numbers than in reality.

Probably code should read beacon transmission efficiency data so it takes it into account :)

just wanted to post a bug report here as well :P
I have the same issue.

Just thought I've noticed that's only an issue with machines having prod modules in them ... but ... reprodicuing the error isn't that easy.
Sometimes adding new new Singularity beacon with two speed-3 modules adjusts the number correctly and sometimes not.
Until now I haven't figured out how and when this works and when it did not.

The mod doesn't use a hardcoded 0.5 ( a fix I made 2 years ago), it reads the beacon effectivity - and I'm seeing 0.75 with the singularity beacon.
Thanks for the update, Yenz, I'll try that.
Are you using the standard Assembling Machine 3s or that Advanced Assembling Machine

In my case it breaks for both types of machines - if I remove the singularity beacons, I get correct calculations. As soon as I add singularity beacons - it starts to go wrong. I'll do some more tests and report back.

I can't make it fail. The other difference with those singularity beacons is the smaller area of affect. (and the advanced assemblers are bigger), so I've played with beacon placement a bit, but can't make it fail (and the numbers always compare ok with the game's production report). Maybe you could get me a screenshot of a case where it fails?

I'll make you a screenshot later that day, but in my tests I used the advanced chemical plant.
Maybe I'm also able to setup a small savegame where one machine is correct and one not... I'll try

Theanderblast - are you on any big Factorio discords? (the official one or any big community people). I think the issue might be related to saves where Krastorio versions were upgraded, cause I can't replicate it on a new save. I can send you my game save then (I don't want to put it publically cause it's an ongoing YT series).

I'm on the main Factorio discord, also Xterminator's, and FactorioMaps & Megabbase

See #mod-making on main Factorio discord :)

We narrowed down the issue and reproduced it - at least for Krastorio 2 big buildings.

i managed to reproduce it:

(minimal save with only those two mods installed)

hopefully that will help you

it seems if you place a beacon manually and put in the modules they won't take into account, but placing via blueprint they will?

Nope, that wasn't the case.

BUT: It has something to do with the position of the beacons:

There the left ones output 8.96/s and the machines on the right 25.76

I upladed this example as well: https://drive.google.com/open?id=1Zob3KkyefHZ0BPOQmJtWGhuXltkKrJeR

There were issues in the box collision check - I have found a proper algo for that task and made a fix and sent it to the author, so far in my testing, I can't break it :)
If anything, it will also now work faster :D

do you mind sharing the change?

Fixed in version 3.2.33, thanks for the help Psihius!

thanks to both of you!
