Troubles Launching the Mod?

A lot of users have been experiencing trouble with the new HoI4 launcher, getting messages like "no descriptor file", being told the mod is for an outdated HoI4 version (1.8), or outright being unable to select the mod to play. This is a launcher issue and not a Kaiserreich issue. Go here for some troubleshooting tips: https://kaiserreich.fandom.com/wiki/Troubleshooting_the_HOI4_Launcher

@KaiserreichDevs I was wondering if it was possible to make the 1934 Naval plan and all focuses like it use the ship designs you actually use (Are considered modern and not "out of date") it will give me those ships so if I start it in 1941 or later I'm not still getting old outdated ships that will instantly get destroyed by France and British Union.

Indian Focus Tree rework when?

tech tree needs to be expanded. The senario is just fantastic, and the story telling is also fantastic. However, the tech tree ends suddenly and there is still so much left in the campaign (which was epic, AUS won the civil war and the US and Japan are now taking on the Syndicate world alone)
