I Love YTtalk
Yeah happening to me also guys, but do not fear my friends I have found a work-around:
Remove 'user' from your channel URL:
e.g.
youtube.com/ZaphodX1
Now the buttons and everything else re-appear
Like if it helped ya 
Goddammit Youtube, I was pulling my hair out! Yay for me being able to give something back to YTT <3
