[2.1.14] Distorted train blueprint

[burninghey]

Visual Bug, jumping wagons. I just noticed something strange. Now I cannot unsee it.
Was a pleasure to read https://factorio.com/blog/post/fff-133 but blueprints seems to not be on par.
Worse, the blueprint preview shows the distorted version *sometimes*

Position after build, while wagon still on it's way but rail ready, right after print:

Blueprinted the print:

I tried to recreate the issue, to avoid there's something strange going on with legacy rails (?) something in the original blueprint someone else created.
Built a small example. Seemed to be fine first, then I blueprinted the build while bots still on their way. That bp has the same issues now:

Thanks for the report however I don’t believe we will be doing anything about this.
