Summary (AI)

Patch 7.21.6 for Xenonauts 2 addresses crashes caused by old save files in the save directory. The update aims to fully resolve these issues, but players can manually delete outdated campaign folders that lack numbered suffixes to prevent problems. Additional improvements were made to stop very old saves from triggering crashes during save game folder scanning.

Tip: expand all for quick scanning.

Another hotfix for v7.21 to address ongoing crashes related to players having old saves in their save directory. This should fully fix the issue, but if not, players can always manually delete old campaigns from their save directory while they wait for another patch (any campaign folder that doesn't have a string of numbers at the end of the name can be deleted).
Another fix to prevent saves from several years ago causing crashes when scanning the save game folder.
