Can I put a complete German translation of your mod into my mod to publishing it?

You don't have to worry about the German translation, because my mod has it then.

Please feel free to write me. Thank you.

This mod will be deprecated with 0.17 release, so it is not important

the definition of "deprecated" might be more difficult than it looks at first:
when someone plays 0.17, it's probably no longer needed, thus "deprecated for 0.17".
BUT when someone still plays 0.16 (eg some old maps, wants to use some other mods which are no longer supported because the author retired, or simply because it will take some time until 0.17 is declared stable), he should be able to easily find and use the mod, thus not deprecated for 0.16
