also, i use auto save each 15 min, but sometimes when it auto save and im working on track 15 as example, the tracks suddenly go all up at the 1rst one, and i have to go back seaching my track 15. really boring 
but yeah this is the best version, congratulation, keep the work :) im very impressed!

Check to see if they are locked. 

Active Region FX will also prevent the splitting of clips.

I've gotten into the habit of locking clips into place lately. There's nothing more frustrating than accidentally moving a synced clip than trying to remember exactly where it was placed. You can use undo of course, but then you lose all the editing done between when the clip was moved and when you actually noticed it.
