Solved after reinstalling CCV, thanks for the advice Thomas SG.
Spoiler :
I found a few bugs in 4.28:
1.) The coffee resource isn't displayed properly. It is pink.
2.) There is no unhealthiness anymore. Did you remove that alltogether?
3.) Roads don't connect to each other anymore.
I have a road from Delhi all the way to the worker.
4.) Whenever I tried to enter worldbuilder, the game crashes - I tried it in different games. Did you add another resource or overlay which may cause problems?

By the way I've got a new DLL for 4.28. I forgot to compile some BUG code.
But that's for sure not the reason for your bugs.
Anyway, I will reinstall CCV and then try again. I am sorry if all that trouble was because I used different terrain textures. 
Sorry for diverting your attention. 
somehow I lost my self..Idont know witch version I am playing now...slowdown a little 

Should I really download an outdated version of my own game? Maybe later... 
It crashes with a segfault in the CvGameCoreDLL.
What a mega map.
