I’ve been seeing this problem in Car Crushers 2. I thought it was related to the Platform-Wide Automatic Translation Experiment, but it’s been happening with Russian which isn’t even stated to be part of the experiment.
There are strings I’ve left out of the localization table that are getting translated to russian, despite automatic translation being switched off. I haven’t been using automatic string collection or AutoLocalize properties, so a lot of unwanted strings are getting translated with no way to turn it off temporarily.
