Make artboard position(x and y) default values an integer not a float
Basically, whenever I export something like an image setting my artboards width and height as a whole number, depending on where the artboard is positioned at a decimal value i.e(x: 1200.232 y:200.623). There is a bug where it will export the image with an extra pixel. So if I've set the width to be 1000 pixels and the height to 400 pixels, for example, it will export this as 1001 x 401 pixels. To fix this problem, I have to always make sure the artboards are positioned at x: 1200 y:200, deleting the decimal values.
Unless of course, the bug itself is easy to fix on your end, this is my suggestion of a way around that problem.
Another idea is to have the repeat function (ctrl/cmd+D hotkey) work for creating artboards also.
