Arrow glyphs got all weird when exported

It’s supposed to be 8 arrows at 45° increments and 2 double ones. All made from one rotated or mirrored component (upward arrow). Is this something that was seen before?

What version do you have?

The latest stable.

Means 1.3.17? This version does not support rotated components.

(Please always give the real version and for betas even the build number)
