I was playing Magnum Opus on and off for the last few months. Now I returned to finish the last bonus levels and I did, but all the histograms in the game disappeared. Does anyone else have this problem?

I checked Shenzhen I/O too, and they are also missing there, so it may be some more general problem with Zachtronics games...

I haven't checked any other Zachtronics games, but I'm experiencing the same problem in Opus Magnum. I just installed it yesterday after not having played it for a while, but I remember them working last time I played.

Today there was an update and histograms did start to work. In Magnum Opus, in Shenzhen I/O still no luck. I think GoG may be bad at updating games, this one has date 14.11....
