fusion-waffle Posted March 20 Posted March 20 (edited) Description Game fails to load main menu, stuck at 57% progress. What Happened I saved my V7.12 campaign, quit the game, upgraded to V7.13, now the game cannot open the main menu & gets stuck at 57% progress. The console in the loading screen displays a repeating red error message: Quote UnityException: get_persistentDataPath is not allowed to be called from a MonoBehaviour constructor (or instance field initializer), call it in Awake or Start instead. Called from MonoBehaviour 'XenonautsMain'. See "Script Serialization" page in the Unity Manual for further details. Further Info Please see attached output.log, although based on the timestamp I'm not sure it captured anything relevant to this issue: output.log Pressing F11 doesn't do anything I play on linux via steam proton, and although xenonauts 2 does not officially support linux, every 6.x stable & 7.x experimental build I've played prior to 7.13 has worked).

fusion-waffle Posted March 21 Author Posted March 21 The v7.12.1 hotfix resolves this for me - thank you! After installing v7.12.1 I was able to start the game as expected, & from a quick test the basic functionality of the game works as expected (loading v7.12 geoscapape save, exiting, saving & loading in geoscape & tactical combat, not hanging during first enemy turn, etc) Quote

Senteliks Posted March 23 Posted March 23 (edited) I resolved this on my mac by re-validating files over Steam (i play over Crossover) - it's a tmp workaround since devs will push fix but if you want to play, try it Edited March 23 by Senteliks Quote

It's probably a different problem, with a similar symptom. It looks like v7.18.17 is an experimental version. Experimental versions are often significantly buggier than stable versions, sometimes to the point of being unplayable. If you are wanting to just play the game, you could try reinstalling the stable version from outside of steam, completely delete your Xenonauts 2 install folder ( steamapps/common/Xenonauts2 ) in steam, switch back to the default public stable branch (steam library -> right click on xenonauts 2 -> properties... -> game versions & betas -> default public version) reinstall the game If that doesn't work, the next thing to try is a full clean install after wiping everything including all of your settings etc If you have a campaign in progress, back up your save games -- for me, they're in C:/users/your_username/My Documents/My Games/Xenonauts 2/Saves from outside of steam, delete the entire game directory: steamapps/common/Xenonauts2 C:/users/your_username/AppData/LocalLow/Goldhawk Interactive/Xenonauts 2 C:/users/your_username/My Documents/My Games/Xenonauts 2 reinstall the stable version of the game from steam copy your saves from where you backed them up back into C:/users/your_username/My Documents/My Games/Xenonauts 2/Saves If the problem persists, create a new bug report thread & attach your output.log & player.log -- see the pinned guide where to find those.

Can you send us your log files so we can check what errors are causing the game to crash? You can usually find this in Documents\My Games\Xenonauts 2\Logs, under a .log file named "output". If you can attach said file when you make a reply, we can check so that's causing the bug. I'd suggest doing a clean install as outlined by fusion-waffle too, especially if you've owned the game at any point in time prior to the 1.0 release. Quote
