Very irritating problem with roads

I want to connect these 2 slabs of road together. But when i use "Complete to..." it throws me that error.
1) Why its not translated?
2) I know what it means, but I dont know WHY it jumps out
3) How to fix

Please help..

OMSI can only fill a gap using one straight and one curved section. S-turns are not possible so you have to create the first turn yourself. The message box says "no matching solution found".

Many thanks for such a quick reply
Also will it be possible in the future to create automagically S-turns? Like that autoconnect for curved sections.

Umm...the algorithm already is kind of tricky, you know...and it still can't connect roads of different height. So the height feature would be much more important first .

Ah of course. Well thanks anyway. keep up the terrific work

Ah yes, one more question. Is there somewhere a street creator? Spline editor some kind? I have the unofficial SDK and there is something like a StreetCreator, but not a editor. And no SDK has been released for streets yet. :/
