I suspected as much, this is a little beyond the scope of factorio support, but do the errors hint anything at a processor, motherboard, memory or HDD issue? I assume the main culprits would be either processor or memory, and i have verified my memory already.

Thanks again for the help anyway

Here's a second log, this one is from a crash during gameplay. I guess its probably another bit flip.

So I'm pretty deep (400 hours) into a space exploration run and got a rather sizeable save file when this crash starts happening with a certain frequency.
Game will attempt to save and it'll crash with this log mid-save and sometimes I'll end up with a temporary save that is corrupted. Sometimes it ...

In that case I'm probably going to have to transition to using tinted decoratives instead of unique textures for each type. It won't look as good but hopefully that will solve the problem.

While this might mean double the work, but a "lite" version of alien biomes could be made for users with ...

I think in between my post a new version has been released. Performance is back to normal, and the mod is working perfectly as intended.
I play with large modpacks so this mod is crucial for understanding long recipe chains, I can't imagine playing factorio without it anymore.

So more news on the "unexplainable stutters", I started to experience them again after adding all the set of NPUtils to my already large compilation. No alien biomes involved. I'm suspicious it might actually be a raw performance issue with factorio's engine due to the massive ammount of sprites ...

Is bot servicing dynamically compatible with new bot types (ie, yuoki, bobs, etc) ?

While FNEI 0.0.17 was stable and pretty much bugfree the new version is very unstable causing crashes, I was forced to rollback. If error reports are of use I can provide.

My main suspicion is that the increased range of decoratives is causing the problem, so it would be really useful if someone could confirm that the do decoratives display option fixes things. (I can't test it myself because I'm not getting the stutter.)

If it is that then the problem is either the ...

I can positively report that alien biomes causes stuttering. After lots of exhaustive testing I nailed the cause of an annoying half-second stutter that occurred every few seconds when running to being caused by being present on any alien biomes region. Transitioning to an area with vanilla biomes ...

This mod is beyond cool. Any news if it'll be update to 0.16?

Thanks for the great job resurrecting these wonderful contraptions. I'd suggest making filter-capable loaders an separate (and more expensive, maybe MK2 circuit-tier) more expensive/complex version for balancing out their incredible versatility.

I like those new upgrades... (spoiler because large gif)
That speed, while using 20MW.

Oh Yuoki is doing the new models? Hist stuff is great, I'm sure it'll look awesome

The problem with the current fluorite is it seems to have been done with a quick HSV adjust. It looks like candy for me. An appropriate recolor should make it purple fading to black, not white fading to purple (if you get what I mean about the gradients).

Which software did you use to model the ...

I am getting the following error:
i'm using a heavily modded version though.

I also am experiencing difficulties with the mod in 12.4. No GUI button and the deconstructors crash.

I was thinking about adjusting some of the production times for intermediate products (machine cases, etc).

Anyway here's a en locale folder with some adjustments:

I assume that could be to simulate losses on the process.

Anyway, I'm in love with this mod, the new content is incredbly fun to play with and also very pretty.

An issue I noticed with the mod is the balance on the craft time. Even complex machines can be assembled in little under a minute ...
