    Six months later still not fixed. 2017.2. We cannot update any of our games for Windows. The alternative .NET build has other issues. Shall we give up using Unity?

    Also reproduced in master mode.
    This withhold us from publishing because of other bugs in 5.5.2, so please, could this get a higher prio?
