I couldn't upload my save through this forum, but here's a link to a save a few seconds before triggering this bug, this time an issue in a trigger tech for Moshine which got researched instantly after researching the planet. Looking at the global statistics, this tech should not have been triggered ...

I expect that this has been reported already, but I could not find any related reports other than https://forums.factorio.com/viewtopic.php?p=651073&hilit=copy+rocket+silo#p651073 but it does seem to be a slightly different issue.

What did I do? Used Shift+RMB to copy rocket silo settings then ...

This report is primarily because of a blueprint I have which was not rotating the body of a locomotive, but there are a few other visual glitches related to trains, including trains becoming misaligned with the rails. If that is deemed to be sufficiently different to this issue, I am happy to submit ...

This is a fairly simple one to reproduce: set a train and blueprint it, setting some parameter (This affects both station names and wait conditions).

What did I do: placed a parameterized train blueprint over an existing train, and set the ...

Found when reporting https://forums.factorio.com/viewtopic.php?f=7&t=126134

What did I do: placed a parameterized blueprint, then before setting or accepting any parameters, double clicked off to the side of the Parameter UI (in my case just one tile to the right of where the blueprint was set to ...

There is some weird behavior when placing parameterized blueprints, where if you set a parameter, then click somewhere outside of the parameter box (I have frequently done this because of muscle memory to double-click to select item at current quality in other screens, and sometimes my mouse will ...

This is a relatively minor visual bug, but I believe it is unintended behavior.

What did I do: Opened map view on the planet I am on, then clicked on another planet through the space map when alerts flashed on. Note that this seems to be replicable regardless of the surfaces you jump between ...

also just observed this, without any gap, dragging over a steel chest, 2 transport belts, and an output underground belt. Haven't done more testing for this at the moment:

I think this has something to do with the new job selection not allowing robots to travel farther than their range while charged. with no robot speed researched, if the origin and target tiles are > 400 tiles away from each other, logistic bots (and probably construction bots, but I haven't tested ...

Since you linked to my post, I think your report is better, but also the reproduction is fundamentally the same (drag belt over belt obstacle, and drag belt backwards beyond that), so I assume this is the same issue. I just happened to notice it when reversing direction and didn't bother to check if ...

when dragging a belt or ghost belt across an obstructing belt, then reversing the direction you are dragging after crossing that belt, it is possible for underground belts to be erroneously placed.

caveats/notes:
- only happens when you start dragging in the direction the belt is facing (ie. east ...

When changing the recipe on an assembler, it is no longer possible to use ctrl+LMB to clear all output slots. ie. circuit condition sets assembler to make gears, then changes recipe to either something else or no recipe, ctrl+LMB will not remove gears in the rightmost output slot from the assembler ...

maybe, not sure if the behavior of being able to read the outputs was intended but my setup no longer works since it was relying on reading output slots. I expect just adding some chests will have fixed this issue entirely though with that report though

I also ran into this issue today, where I was setting recipes by circuit condition.
in my example I had connected the foundry to 3 combinators, to produce engines (if ingredient <100: output 1 of that item's signal in each one, red wire in, green wire out). When I ran into the issue, the inserters ...

when dragging a ghost belt (setting for Pick ghost item if no items are available), the exit underground belt may not be placed, even when the input is.
Conditions to reproduce: have only 0-1 underground belt segments and at least 2 transport belts in your inventory

To replicate, set up 2 parallel ...
