Brush stroke offset error

[Baard Vidar5E80]

I have a rather large artboard (420x6000mm). Whenever I try to use a brush to stroke an object, the stroke brush is offset in regard to the path. See screengrab. 

What is wrong?

Can you show the appearance panel for that object?

Also the brush options?

[Baard Vidar5E80]

Any ideas?

add please an Appearance panel with the object selected. Now it's with "No selection", so some details can be missed.

I'm seeing this in all art brushes in large canvas files. I can only find one other post about it and nothing on uservoice, which is strange as it seems like such an obvious bug:

Guess I just have to work around it somehow..

[Baard Vidar5E80]

The brush is a standard arrow brush

I think it has something to do with my document. This is an object with the same stroke created in a standard A4 document:

Here is the same object copy+pasted into my large document:

But I can't find anything wrong with the settings.

Baard,

It seems to be some kind of corruption, which can be either in the document itself, or a general one, maybe affecting only large Artboards.

The way things look corresponds to an effect (Effect>Distort & Transform>Transform with a horizontal Move setting) but such an effect would have shown in the Appearance palette which Doug asked for.

You can try to create a new document with the same size and copy the artwork over and see; failing that you can try with new artwork in the new document.

Thanks Jacob! I've tried all of those things. Seems this is always the case with an artboard of my size. I guess I'll have to make it in a smaller artboard, outline strokes, import it and scale it afterwords.

Do you need here to use exactly Brush stroke? If you don't plan to use any comples shapes for the strokes, maybe you could get the same "arrow-shaped" line using a Stroke Profile? 

this line is created on tha artboard with your size (420x6000)

the artboard is 420x6000

[Baard Vidar5E80]

Good idea!

I just added an offset path FX to it and changed it to round, seemed to cure it.
