hey! thx for your PR. Are you able to read/write every of this languages?

[forgodtosave]

Hi, not all of them. But de, ja, ru, hu should be correct and also nl and fr but here I'm not 100% sure.

[meteyou]

pls remove all translations, where you are not 100% sure. these should then be translated by native speakers.

Honestly i would prefer to remove the changes to ALL translations but german and (obviously) english. A lot of the other translations are outdated anyways and require an overall rework of a (at best) native speaker of those languages.

I removed all translations except for en and de and languages where I asked a native speaker if it is correct.

[meteyou]
