I find out that the libmpq implementation we used had problems to load many files out of the MPQs.
This is the reason why noggit cashed when you fly around, because it wants to load a .skin file that is not there. And also the reason for the missing textures and the with interface in the enUS version.
I have switched now to stromlib and this bug is gone.
Our main problem in the moment is the we lost out SVN some weeks ago (server went off without any warning) during we make many changes on the code. Switch some libs, move classes and change the hole OpenGL implementation. At some point we get the error of a transparent ground. And in this moment the svn went of. So we can not go back to a earlier version of the code and have to find the problem. And we are all not the great OpenGL guys
But in the moment I spend many times to get this skills and work on a new stable version of noggit3.
So please be patient.
