I assume that the issue arises when you have both a railgun and another entity in the same blueprint. It is probably not worth adding an extra check or whatever to make it possible to rotate a bluprint which only contains a railgun

What is still required to approach this bug?

The "bug" i see happening here is the difference in the underground when you attempt to make a corner in the belt.
When you run into a belt (or as far as i can tell any other obstacle) you still place an underground, which results in the sideload you can see in the video above.
This is different ...

It was requested by speedrunners to automate some checks on uploaded speedrun save files with replay data. I guess they will be using it to automate some checks...


Thats correct. We want to automate it and most importantly make it easier / possible to run the replay from a headless server.
Lets ...

i really would like to know how exactly this is a duplicate

this is the last for now, i will go back to the others, i realised they are lacking some info.

when doing some stuff, the undergrounds somehow vanish? i have a save file if that is necessary. i would expect it to no vanish the undergrounds.

should be fixed now

okay, something screwed my post.

TL;DR
When a gate is open, they should not get damaged by a rail gun shot.


What?
Currently, there is no good reason to use gates on space ships, especially when using rail guns. similar on the planets.
Maybe even partially opened gates could be missed by rail guns?


Why?
There is currently ...

this is not the same? this is not about the general splitter behavior change. this is about the bugged missing underground when interacting with the splitter on a curve

The issue here i think is twofold:
1. the underground in front of the splitter is treated as being connected to the splitter which results in the underground being added in the first place
2. it both downgrades the existing ...

the splitter seems to consider the underground to be connected to it, resulting in this weird mess of undergrounds. which also somehow makes the underground go the wrong way, which i assume happens because of the "switch" in which ...

although that only seems to happen when downgrading a belt.
seems to only happen when the underground is too long for the upgrade

how about this: not sure if that is the same thing though.

that wasnt even what i was trying to reproduce for the clip.

i think the problem here is similar to starting the belt drag on an already build belt (or rather, it is similar to what happened in earlier versions). when a belt is ...

i would have expected smart belt to place an underground before the splitter. similar to the underground that is placed when running the curve into a belt.

it would be good to know what this is a duplicate from.
