Thank you for the bug report.
Sorry, I couldn't reproduce this bug (switched to German also). However I've made some small fixes that may resolve the problem. Just released a new update.
Would you like to update the mod and check this again?

I've just received a report from another gamer that this last update fixed the bug. Please check it.

It works when I open it after starting the game, but as soon as I was in the (improved) mods panel and toggled some mods it looks like that.
The complete log:
http://pastebin.com/AuBHcvuQ

I think I could fix it. Now it shoud be compatible with Improved Mods Panel.
Just released a new update.

Together with the native UnlockAll mod it creates issues (double milestones etc.)
Could you make it compatible?
I wanted to create a city with all unlocked but with "normal" money settings.

I've just run it together with the native UnlockAll mod. It worked as expected (i.e. all was unlocked).

Would you like to check this again or explain in details what kind of a problem do you have?

It works, but the log is full of "double milestones", "double whatever" entries.

I couldn't find any suspicious entries in the log file.
Was it ...steamapps\common\Cities_Skylines\Cities_Data\output_log.txt that you looked into?

Yes.

Technically, there should not be compatibility problem.

Look.
UnlockAll mod sets PopulationTarget to 0.
Difficulty tuning mod multiplies PopulationTarget by some coefficient.

Regardless the mod loading order, the result is the same - zero.

May be there are some other mods that cause "double milestones" issues???

12 december - I played CS early in the morning. then windows 10 asked for an update ; oke, stopped the game, took some coffee, wanted to play again... not just cities skylines, but also other programs had become major problems. lost some files. My graphic driver ? windows deleted it, and used its own, I noticed later.

So far I fixed everything,
Since then I can use my computer again, and start cities skylines, well, just the headmenu,
I could not reload my cities

- 16-12-2017 report update, after trying to get the game work, I notice I can always start a new city with all kinds of mods, I can save it, but I can never reload it later ! when the city is almost reloaded... some kind of RE-mapping bug.-

The report (one of the reports) is veeery long, the error is at the end, I think !, so here is the end of the report :
