Fast replacing underground belt is not working as shown as in tips and tricks section. See attachments for more details.
Reality: Note: No mods

Not a bug. What is shown in the tips and tricks is a "belt power replace" mode which is triggered if first placement (not by drag) places belt over underground or splitter. In the belt power replace mode undergrounds and splitters during the drag are replaced. Since you started on the regular belt, you are in regular belt building mode and so undergrounds are kept.

This is not what is happening. I can confirm the issue the OP is having. Have a look at the video again. The OP is clearly starting on the underground belt. The first one gets replaced no problem, but the second half is not replaced.

From what I see in the video (paying close attention to the red dot indicating a mouse click), it is as boskid describes for the first attempt. But it seems after this, a "belt power replace" is attempted which replaces the first underground, and places belt up to the second... which unlike the tips and tricks version, does not get replaced.

Can confirm op. Second ug won't get replaced.

Hi, thanks for response. First of all sorry for unclear gif attachment. There are two attemts indeed. So I decided took another demonstation, pipes included.

First line - dragging from existing pipe/belt over undergrouds/splitter -> nothing gets replaced as expected as.

Second line - dragging from existing undergrounds over other end and splitter -> Only first undergrounds get replaced (even pipes). From my understanding, what is shown in Tips&tricks and what boskid wrote, this is a bug, all undergrounds and splitter should be replaced.

Third line - simply clicking, not draging -> everything gets replaced as expected as, but this is not the "belt power replace" that we are talking about i suppose?

Then i tried with "Lock belt building to straight line" off. And it works as boskid described as! Except for pipes...

So, my questions are these:
Is "belt power replace" supposed to work only if "Lock belt building to straight line" is off? If yes, then it needs to be clarify in Tips&Trics or settings. If no, then it is a bug.
Is the same principle applicable for pipes as decribed as in Tips&Tricks? If yes, then pipes are buggy.

Gif quality is lowered down to be smaller size, but clicks are more vissible (yellow dots).
Thanks for the time and effort you are putting into the game!

EDIT: I forgot to include splliter in "Lock belt building to straight line off" gif, but it gets replaced as undergrounds gets.

Hello, the belt power replace was fixed for the next release of 1.1.13.
With pipes, it was never implemented or presented for them to work this way, so it is more of a feature request.

Thanks for the fix!

I don't know, but in the Tips&Trics it says "features", so i supposed it shloud be working even for pipes replacing pipes to ground.

Oh, lawyered, ok, fixing this as well for 1.1.13

Nice, thanks!

You are the best dev team ever!
Thank you very much!

Also, hopefully you fix the grammatical error! It should be "feature" not "features".
