Hi!

I'm making quite a large map (about 750x1000).


For some time now I'm working on the rivers.
First I did the Italian rivers, all was well.
Then I worked my way up through france, after that south germany.

Then after a test run, occurred CTDs when ones view is above certain areas.
I recursively masked certain rivers and eventually found 3 rivers causing these CTDs.
Then I had a closer look to one of these rivers.
I tracked the CTD down to one section of that river.

Now comes the mysterious part.
The CTD causing section is just a short part from the source of the river southwards. There is no branching or other unusual things.

So I'm puzzled.
At the moment I have no time to do further test, so my question:
Has anyone experiences with this problem?
(Is it some strange hardcoded limit?
Causes the large map this problem?)

Thanks!
