Hearts of Iron IV | Patch 1.18.2
Generals!

Batya here with another patch.

The focus is around Czechoslovakia’s content that was recently released with Peace For Our Time. Besides that there have been a few crashes that were fixed and included in this patch. I also want to extend a special thanks to the wonderful team behind Peace for our Time and all the balance changes, bug fixes, and other additions that they made since release!

This is currently the last planned patch focused around the release of PfoT, but any additional issues will of course be picked up in future patches. We hope that you will enjoy these changes and as always let us know what you think and if you find any other issues do let us know!

As a final note, the team added a little secret and wanted to provide a little hint so here is my (maybe not so) cryptic hint: A.E.I.B.U.

Happy hunting and see you on the Sudeten front!
