Gotta love third-party hosted services:
The GitHub integration of Crowdin deleted my translation files after I moved them in the repo and there appears to be no way to restore them (not possible to undo in the interface and the support claims they cannot restore backups... wtf)
Guess I have to finally look into moving to a self-hosted solution so I can just resolve such issues myself although it's kinda sad to see the translator credits and small translation-community around it that my open source project gathered over the year probably break down due to that. :S
