-New tag added for event XML’s. (Check “REMOVAL_TEST” event for example use)

There's a few other problems as well, including engi medbots not working and GFX like laser impacts missing.

Can we get the old 1.5.x installer available please? It worked just fine.

The januray patches broke the opengl version.

It crashes after loading.
Sometimes, the music starts playing but the menu screen is black.
Something gets loaded because I hear the rollover when I move the mouse.
And then it stops working.

The only log I found is:

Reinstall and disabling fullscreen from settings did not work
Adding -directx to shortcut seems to fix it.

Changelog for Patch 1.6.7 / GOG-18661 (Windows) / GOG-18662 (Mac) / GOG-18662 (Linux) (added 16 February 2018):

- Fixed numerous Linux issues (failing animations, Engi Nanobots not working, etc.)
- Fixed crash on exit on Linux
- Possible fix for restoring monitor resolution when quitting from Fullscreen
- Possible fix for rendering issues on Intel HD 4000
- Possible fix for other rendering issues on Windows

Loading time after start is incredibly slow. I wonder what's being loaded at all? Why these simple graphics are not loaded dynamically?

Other thing: fullscreen settings are not saved on Mac OS. Every time the game starts in windowed mode.
