Is there a reason for this? I've seen it in only one song that i created, it occured only at specific song not in any other with bend and * . Also i should mention that this bend was connected with another note on string example G string   9(fret)/2*------------7. I dont know for what star stand's for in eof.  When i shortened duration, just so that bend wasn't connected to another note, in this ex. 7 everything was fine, and star was gone. In other songs i have seen same thing but rocksmith wouldn't crash at that exact spot like here or crash anywhere at all, this is first time rocksmith crashed for me. Before i tried this, i have tinkered with various solutions someone mentioned here, not including lyrics, generating others files with different names of dlc and god knows what.  

The "*" symbol means that there multiple tech note on the sustain. Look at what are the tech notes on this note and see if by moving/deleting them the problem is still here or not.

I fixed it, and now it works great. But i wanted to know what it is, and why it crashes on only one song.

If shortening a note made the * go away, that means the tech note no longer overlapped that regular note, so it no longer had any effect. You can see what the tech notes are by pressing F4.

Didn't know about that. But now i don't understand what i'm seeing. I can delete all the bends (green or red), but actual bend is still there. Is there real manual for eof, because one that came with eof is basic?

The complete manual is in the Help menu. All menu functions are described. There are tutorials on the forum about how to use tech notes.

I have looked into eof internal manual, but to me this is basic explanations how to make song, like it is done so it can be said that is there.
