Encountered this problem several times now, but it is also problematic for exporting for developer. Every time I have an asset that needs to be rotated in different positions on different artboards, exporting it for dev, it keeps the original parameters of the asset pre-rotation, ie, a 600px wide x 200px tall asset that gets rotated 90 degrees, on export, it keeps the original 600px wide x 200px tall even though it should be 200px wide by 600px tall. Also had to copy and paste from illustrator as a work around, but a reset to remove the rotation would be very useful.
