The Hearts of Iron IV version of Kaiserreich is still in alpha and yet it already contains thousands of events and dozens of focus trees so inevitably there will be mistakes, please report them here: https://github.com/Zankoas/kaiserreich/issues?utf8=%E2%9C%93&q= in as detailed a way as possible. Please don't report them anywhere else, it makes our lives much easier when all bug reports are in one place.

Translation efforts are under way in Russian, German, Spanish, Danish and French. Help is wanted for all teams, and we would love to open up other teams as well. Note there are several unofficial translation projects on the workshop, they are wonderful, but we of course can't vouch for their quality, so use at your own discretion.
