I found a simple instance of this bug (in 2.1.14) that doesn't involve a splitter. There's 4 possible combinations of (new belt facing left/right, new belt started from left/right of existing belts), and 3 of those combinations trigger the bug.

This issue also occurs when toggling "show unresearched" after opening Factoriopedia from the technology screen (which pauses the game while it's open). This is probably more common than pausing the game with the pause key; not sure if it's common enough for this to be worth fixing though.

Thanks! Looks like you only addressed the beacon upgrade case, not the machine upgrade case I mentioned in the edit. Should I make a new thread for that case?

Have you tried using shotguns? They're not as good at this as e.g. grenades, 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 ...

Fair enough. Could you consider moving this to Ideas and Suggestions? I feel like the tile transitions are jarring enough that it might be worth another look by the graphics team.

This also applies to labs.

Also note viewtopic.php?t=134337, which describes other limitations of the potential crafting speed system.

Yes, that setting was on; I wasn't aware of it before, thanks for mentioning it. I'll try disabling it and see if that helps.

However, having that setting disabled might cause the opposite problem: if the setting is disabled but Muluna had been enabled while it was updated, the newly-installed ...

If you have a disabled mod installed, and you update the mod, sometimes it'll happen that the mod has new dependencies that get installed when it's updated. In this case, the mod's new dependencies will be enabled even though the mod itself is disabled.

As a concrete example, Muluna recently added ...

To reproduce: open technology screen, select any research that unlocks a building/item, alt-click on the building/item to open Factoriopedia, press back button on mouse, press forward button on mouse.

Expected result: the forward button should keep the technology screen open and re-open ...

The clouds on the Nauvis and Gleba backgrounds behind space platforms look great, but I feel like Nauvis has too much cloud cover. It makes sense for Gleba to have lots of clouds since it's constantly raining, but for Nauvis, I think the amount of clouds should be reduced by maybe 25-50% so you can ...

Looks like this idea already got rejected here, sorry: viewtopic.php?t=133547.

I don't know whether this is technically a bug, but I'd like to add that I don't particularly like the look of the new tiles, especially the transitions between tile types. I prefer how it looked in 2.0.

In 2.1.9, there's some visual glitches when the player takes off in a rocket. I've seen 2 forms of this, not sure whether they're the same bug:

In one launch, it looks fine at first:

But then, part of the top part of the rocket turns black, and the whole ...

When the player takes off or lands, there's a visual glitch in 2.1 (vertical lines in the cloud textures). I don't remember seeing this in 2.0. It happens on several (maybe all) planets; I've attached screenshots from Nauvis.

Looks like this might be a duplicate of 134174?

I think this is a duplicate of 131868 (or if not quite a dupe, it's very similar).

I've also run into this limitation and would like a solution if possible.

Another possible solution would be to add a priority to each space platform, and platforms would send items to platforms with higher priority even if that means they end up lower than the amount they request. E.g. in the OP's ...

I'm seeing this on Linux on X11, at least on Nauvis (I haven't checked whether it shows up on other planets for me). It only shows up at a specific angle; 90% of the time the planet looks fine. Attached a log file.

I love the feature of 2.1 where, once you place a ghost beacon or module, hovering over a machine shows what the crafting speed will be once everything is built. But there's (at least) one case where this info isn't shown: when upgrading a beacon to a higher quality. To reproduce, place a beacon ...
