undo is acting buggy
- 
 Hi, I am having a problem lately where ‘undo’ will revert back past many changes I have made instead of going one step at a time. I don’t know how to reproduce it because it seems to do it randomly. 
 I have Windows 7 64bit.
 If I close Notepad++ and reopen it, it’s usually fine again for awhile.

 Here is what it says right now but I’ve closed and reopened it- do I need to copy it after it acts up again? Notepad++ v6.8.8

 Hello None-Ofyourbusiness, no this is just a quick overview which os, npp version and plugins are installed. 
 Helps to try to reproduce what happens.Cheers
