[Tex/LaTex] The [H] doesnt change figure* placement, printed on page instead

floatsgraphicspositioning

I'm trying to modify my figure placements, but the [H] (and [!ht], etc) isn't working. It has no effect on the figure placement, and I get the text "[H]" added just before the image.

MCWE:

\documentclass{mn2e}
\usepackage{float}
\usepackage{graphicx}

\usepackage[english]{babel}
\usepackage{blindtext}

\begin{document}

    \begin{figure*}[H]
    \centering
    \includegraphics[width=0.8\textwidth]{fig}
    \caption{Some Caption}
    \label{fig:1}
    \end{figure*}

\blindtext[10]

\blindtext[6]

\end{document}

Result:

And I'm using TeXShop 3.6.1 on OSX 10.11.2

mn2e and its replacement mnras class disable the float options. As with many publisher classes they intentionally remove options from the author to enforce a house style.
