The download page claims that it 's version 2.1, but it's lying (version numbers are sometimes weird on GOG.COM).

It's apparently an older build:

- The the Linux installer contains a ZIP file, and all files within it show a timestamp of 2022-01-17 (2.1 was released over a year later, right?) 

- Both the Linux and the Windows versions crash immediately if the 2.1 version of the R18 patch is installed; the 2.0.3 version appears to work fine (I only did a very short test).

Would you please update the version on GOG.COM?  Pretty please with a cherry on top? :-)

(BTW: is there any way to find out the actual version number of the game? Some games simply display it on the title screen, which I find immensely useful in situations like this...)
