S.T.A.L.K.E.R.

The launcher works and installs almost all the necessary mods (I get a "no valid game data" flag in MO2 for 10 mods and their folder are indeed empty except for a .ini file), the game launches and plays, but inserting a weapon part into a weapon crashes the game every time.

The error message is about item_exo_device.script:21 attempt to get exo_mcm (nil value).

I fixed it by installing GAMMA in a real Windows install and then manually copying the content of the folders of those mods (just GAMMA/mods) that were flagged by MO2 from the Windows official GAMMA launcher to my gamma-launcher Linux install. Some of those flagged mods were indeed correctly downloaded by the official Windows GAMMA installer and their folders were filled with files, so I simply copied those to my Linux install.

Namely, the mods referencing exo suits and exo suits noise were the cause of my crash (no idea what installing a weapon part in a starter weapon has to do with exos).

Now the issue of part stripping and reinstalling is fixed!

I still have issues with MO2 itself (I can't activate/deactivate mods, doing so freezes MO2 and the changes simply don't stick; also running Anomaly Launcher from MO2 doesn't really work, as it actually launches only when I click Run and then CLOSE MO2), but at least the game is playable (for now).

See you in the Zone!

Also watch Shadow of the Zone by Evan Royalty on YT, pretty nice short movie set in the STALKER universe
