Not a mechanical bug, but I noticed a misspelling: "Sudetan" should be "Sudeten".

Oh yeah, That's odd I use the correct spelling in the comments but the localisation is misspelled, It shall be fixed in the next update

Some linguistic and other corrections based on your recent update on the page and the new preview maps:

Neue Nordisch -> Neunordisch or Neonordisch
Posen -> Posisch (I mean "Posen" are the people living there)
Deutsch-Balten -> Baltendeutsch (same issue as above + it should not merge with Prussian. If anything Prussian should either stay or even merge with Hochdeutsch)
Pannonischdeutsch -> Pannoniendeutsch
Dinarischdeutsch -> Dinaridendeutsch
Weißedeutsch -> Weißdeutsch

Edit: "West Germanisch" -> "Westgermanisch" (Tho I'd just leave it as "Germanic" or "Germanisch")

Wolgadeutsch should only follow the volga river as discussed.
Kaukasusdeutsch should also spawn in the southern caucasus.
Carniola should go austrian or ultimately Hochdeutsch within the context of Eu4 while Switzerland should go swiss if germanized, including the romanch and french parts (perhaps even Valtellina could go swiss if force-converted).

Found a bug regarding frankish culture spawn. https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1388901148

Here's another one. https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1388950133
I assume it's the culture spreading event.

Was able to reproduce the bug with Schlesisch.

@Recognizable Sorry, it appears I couldn't seem to decide on whether it should be Frankish or Frankisch with the events, it should be fixed soon.

@Argacyan Shlesisch was referencing the wrong localization strings, it should also be fixed soon.

The event for Sudeten fires correctly, but I spotted a tiny misspelling ("Sudetan") in the event description.

I noticed that since I started using this mod switzerland and / or the three leagues culturally change or convert the area of the grey leagues very early on. I feel like switzerland and the grey leagues, or just the swiss germanic culture, should be barred from the decision "Ostsiedlung" or from the mechanisms of the mod so to say.

The reason is that historically seen the germanisation of the area in question was so slow that it became majority swissgerman after the start of the 19th century - so pretty much at the end of the game timeline. Any earlier convertion as well as the swiss confederation in a general sense becoming fully german is immersion breaking and I don't know how likely that would have been in a given AH scenario. The kind of german settlement we're talking about could have only happened in any larger sense if the swiss state seized to exist I think.

@Argacyan Hmm, not really too sure why I both allowed that event to fire for a Swiss country and made the MTTH 50 years (Shortened to 35 years), I'll raise the MTTH to 150 years and only allow that to fire for Standard German countries in the next version.

I can't do North German Confederation mission. I've completed all the requirements, but it is grey. (It shouldn't be, because i completed Saxony mission).

The Occitan rebellions just won't stop, I've seen at least 4 events from the same city and the events just keep happening every few days. I don't know if this is a bug or not but regardless it is unplayable.

@The English Crusader reboot the game and ensure you are on version 0.3.1 and it should be fixed.

The event seemed to fire fine, But now my save has been rendered useless as it insists i don't have the mod enabled (i confirmed it is enabled in the content menu) and all of france now has no culture.

@The English Crusader I haven't touched any of the culture IDs since the mod was first released, so something has gone wrong on you end, can you check that the .zip file is present in your mods folder?
