i must have messed up my Portal files.
Launching a map from Hammer results that the map does NOT end.

If i enter the elevator for good bye, it looks like this (black floor):

And Portal seems to miss something:

I had a backup copy of the folder

sdk_content\maps\instances\p2editor

and pasted all back - but no change.

Any idea welcome.

Edit:

I should mention, that i can enter the lift, the lift starts up, but goes on endless - during that trip up is displayed the message regards the missing level in 'elevator_motifs'.

I wouldn't worry too much about the "elevator_motifs".

Since you are using the PeTI elevator instance, the elevator will work normally once you publish the map into the workshop.
