Fixed some OpenGL lighting issues when light occlusion was enabled.

Was it enabled ?

With Wube paying so much attention to optimisation as well as obscure bugs,
and the change you report being quite significant,
and indeed there seemingly being no change listed that should have caused this,
(you aren't on Mac, or using OpenGL, are you ?)

Wube would likely be glad if you made a ...

What seems faster to you ?

Right, Plasma is a fluid, even if cannot be piped normally.
(I guess Wube could still remove temperature from all other fluids, or rework Plasma (Heat Pipes using a different mechanism anyway).)

Going back to centrifuges, I can't believe I forgot to link this very «Factorio scaling» story ...

Ah, my bad.

Well, that's an option, even though it would be a lazy one.
(Certainly would fit someone using dystopian corporate terms like «force player engagement». Hopefully Wube isn't like that.)

I was more thinking of more unique ones. More in the vein of More A chievements than Stupid ...

If all of the achievements in your game can be beaten in a single play-through, then your achievements aren't varied enough.

(Some of them should be mutually exclusive, or require mutually exclusive starting game settings, or different game modes.

In the case of Factorio, consider the official ...

One heavy-handed solution to this might be to have the player select a fixed recycling recipe. (Think assembling-machine-like rather than furnace-like.)
A less heavy-handed solution (but requiring extra work for Wube) would be a quality-blind recipe selection.
Another interesting solution ...

In my opinion, the angle (360°/16) does not have any practical value in the game.
All useful angles in Factorio equals to arctg(m/n) with some small integers m and n .
For example, the "half-diagonal rail" angle is not rail-specific: some of my defense structures have wall borders with the ...

TL;DR
Pressing these keyboard shortcuts would order the train or space platform to immediately go to the previous/next station in their list.

What?
Importantly, you would NOT need to open the Locomotive view / Space platform hub to give that order.

Some gameplay implementation questions ...

Oh, thanks, since it's 'hidden' in Debug hotkeys, and doesn't have 'train' or 'locomotive' in the name, I didn't find it.
Just tried it.

I'm not sure it does fulfil the most important requirements : I would say that one of the biggest requirements here seems to be the ability to not have to aim ...

Some new ones I found :
(no idea about their quality)
Flip-Flop Train Driving Mode
Train Toggle
Automatic Manual Mode

Yes, please !

Also for Space Platforms !!

Some new mods that do the same thing, or a related thing :
(for trains at least)
Flip-Flop Train Driving Mode
Train Mode Switcher
Train Toggle
Automatic Manual Mode

Yeah, so was quality itself. But in some ways it's easier than quality, so, combined, the result might be easier too ?

My opinion is that fluid sushi are quite difficult for most players because they often require internal knowledge about how the game treats things beyond what is necessary to ...

EDIT 3 :
8.) Barrels :
(maybe the biggest snag)
it's one thing for barrels to not preserve fluid temperature, and it be reverted to the default 15°C upon un-barreling,
(though mods, and even Space Age's Fluoroketone, have to use separate fluids / items as workarounds)
but it would be much ...

Adding another mix-able property to Fluids seems like a lot of Effort, would take extra calculations each tick that the Fluid system is active
Well, only Wube knows how expensive it is in practice, and while this was one of the reasons why they thought about removing temperature completely , note ...

Speaking of quality modules for fluid recipes and 'legendary fluids',
please also consider a deeper solution :
Fluid Purity : an Item-Quality-like mechanic for Fluids

TL;DR
Quality implemented for Fluids in a freely-mixing, less-processing-blocking way.

What?
Fluids would now have a Purity value.
It would be treated mostly (but not exactly like) as Item Quality in most recipes.

With values of
90% Purity ~ Normal Quality
99% ~ Uncommon
99.9% ~ Rare
99.99 ...

It's trivial to mod in new values for weapons,
while I'm not even sure that adding something like this is possible without binary hacking ?

And Wube has made changes in both 'categories' before.
