I'm not sure that it is a bug, but I certainly had the same problem: 1. The auto-request only sends any given item if a whole rocket can be filled with it — at first, I thought I was doing something wrong, as I wanted to send only the required resources to build the platform as fast as possible. The...

To be honest, I have noticed the symbols for the first time as well
I haven't built a lot of two-way rails before, so TIL!

I tried on MacBook M1 Pro with macOS 15.0.1 - couldn't reproduce

I think this is the precise problem:

Before: After:

To me, it looks more like a problem with signal placement, but I might be mistaken.
I've moved some signals around, the train has no problem finding the path, take a look if it solves your problem

Quick update: tested on a clean 2.0.12 version - same behavior, will update the thread name Blueprint to quickly reproduce: 0eNqlldFu6jAMhl8F+WqTykRKQte+yjShUrwSLU2qJGVDqO8+h8I4R3Ako3NXJ/H3O8rv+ggbM2DvtY1QHUE3zgao3o4QdGtrk9Zs3SFU4GttYMxA2y1+QyXG9wzQRh01Thmn4LC2Q7dBTweyS2akVDsP0fWQQe8CpTibyIRZ0rEDVPO...

I've tried to do exactly the same on my Windows machine - and couldn't reproduce

I've attached the log and the save file I've just created

Some notes:
- I'm using a MacBook with M1 Pro
- I've created a clean new game and used `/cheat` to get the items
- I've pasted the blueprint attached to the first message - got the same result

Description When the selector combinator is set to "Sort ascending" and there are at least 8 signals in the network, the returned value of some indexes is wrong (see example below) Example Notes: - on the left side all the selector combinators are set to "Sort descending" - ever...

I'm sorry for creating the bug report before fully testing it, but the root cause really seems to be "placing the train out of order". To update on the original post: What did you do? 1. Place a locomotive 2. Configure its name/schedule 3. Place the second wagon 4. Place the first wagon, c...

UPDATE: Please read the first response instead, as it provides a more compressed version of it What did you do? 1. Create a blueprint with a parametrized "train station + train", where the fluid is parametrized 2. Place a blueprint, select a fluid, e.g. water 3. Wait for the train to be p...
