Lowercase gamma in mhchem environment with fontspec

I'm trying to use \gamma inside the mhchem environment, and it refuses to render the correct glyph. Alpha and beta work, as does Uppercase \Gamma. I have tried this with other fonts e.g. Roboto and the same behaviour occurs.

Is this a bug and is there a workaround? MWE:

\documentclass{article}
\usepackage[version=4]{mhchem}
\usepackage{fontspec}
\setmainfont{CMU Bright}
\begin{document}

\ce{\alpha}
\ce{\gamma}
$\alpha$
$\gamma$

\end{document}

The output is the following:

using LuaLatex. With XeTex, a crossed box appears.

EDIT:

Logfile link here: (XeTex) Logfile (LuaLatex)

[! Output of \printchemgreekalphabet]

FINAL EDIT: Shamefully, updating to the newest mactex distribution fixed the problem. Thanks all for your help.

Are you compiling with Xe- or LuaLaTeX? – TeXnician Jul 14 '17 at 15:51

It clearly works for you OK then. Any ideas why this might not be working on my setup? No errors or even warnings are thrown on my machine. – user1654183 Jul 14 '17 at 16:19

Show the log-file. At best from lualatex. – Ulrike Fischer Jul 14 '17 at 16:30

Show the complete log-file. The interesting parts are not in the snippet. – Ulrike Fischer Jul 14 '17 at 16:56

Does \printchemgreekalphabetshow the complete alphabet? – mhchem Jul 15 '17 at 05:43

Umm, you claim the log file was produced by LuaLaTeX, but the header line says it was compiled with XeLaTeX. By the way, if I compile your file with LuaLaTeX (MacTeX2017, LuaTeX 1.0.4), I experience no problems at all. – Mico Jul 16 '17 at 14:39
added LuaLatex logfile too – user1654183 Jul 16 '17 at 17:07
We cannot see the image, because it's on DropBox. Insert it with the correct interface, please. – egreg Jul 16 '17 at 17:13
I tried that but it exceeded the char count for a post. The Dropbox link should ve viewable to all with the link? – user1654183 Jul 16 '17 at 17:47

I'm voting to close this question as off-topic because the issue was solved by updating software – egreg Jul 16 '17 at 19:46
