resizing slashes inside \combgame{} does not work inside align environment

[brettpim]

In

\begin{equation}
  \cgup^{n+1} &=  \combgame{\{0| \cgdown^{[n]}*\}}
\end{equation}

The slash is increased in size to match height of options of game, but in

\begin{align*}
  \cgup^{n+1} &=  \combgame{\{0| \cgdown^{[n]}*\}}
\end{align*}

it is not resized

If you use \cgslash instead of a vertical bar, it will resize properly:

\begin{align*}
  \cgup^{n+1} &=  \combgame{\{0 \cgslash \cgdown^{[n]}*\}}
\end{align*}

I agree it'd be great to find a better solution, but this serves as a workaround in the meantime
