ACTIVE Flush scenery indexes

[Christian Floh]

Hello,

I have the following problem:

I clicked on the button "flush scenery indexes" at the tool-menu.

Afterwards, I read that it was not "good"  / not recommended to click on this button 

While I am flying, I always have the impression that something is wrong. 
It doesn't look so good (landscape and so on) as it was before.

So can anyone help me, to restore my scenery ? 

What can I do?

Many thanks,

Christian from Germany
