I discovered the same bug about two weeks after you.
Fun fact/story, if you have a discord channel that synchronizes the chat you can post img=file. (or img=file/ which is what I discovered but works the same) to the actual chat. if you do that all current players will crash and anyone who rejoins ...

Maybe not a bug, just and inaccessible sprite.
The sprite for automation science technology is not available via the rich text ( [technology=automation-science-pack] ). While this is logical as there is no technology for the automation science packs, the sprite exists as \data\base\graphics ...

After I accidentally hit the upload/download button I cannot open the helmod GUI. I get the message shown in the attachment.

It ran into a couple issues: the first being that a lot of stuff is closely tied together and has to be deterministic (i.e. run exactly the same way every time, regardless of core count, etc ...

So I've stumbled upon the option to allow increased zoom at the bottom of the debug menu. This increased my UPS to around 400-450 (it's fluctuating quite a bit now) when fully zoomed in.
Furthermore I've read a little on multithreading and the real culprits are the belts, which are not multithreaded ...

The game is only slightly multithreaded, but mostly monothreaded. Don't expect your CPU go 100% unless it's a monocore :)


Yeah, I see what you mean, apparently core #0 is at 100% while the other 7 cores are not being used at all.
I could overclock, but that wouldn't yield a big increase in ...

So I've increased my game speed with /c game.speed = # since I want to drain a 40M copper deposit that's in the way of my new steel production line a bit faster.
The issue is, when I set my game speed to higher values, starting at 5, my UPS seem to be capped around 250, when it should go up to 300 ...
