Yep, totally happened to me. Lost 100+ subscriptions. Had to find and re-add everything I follow by hand.
Also, had a fun bug recently with the G+ Page/Profile bullshit where I deleted my Youtube Channel account so it would stop asking about G+ integration at the cost of no longer being able to post videos or comments. (However, jokes on me, as they just forcibly integrated my G+ with Youtube ONE WEEK after I explicitly deleted my Channel account to prevent exactly that from happening. Thanks, Google.) It didn't erase all of my subscriptions, but it made them all nonfunctional. My feed was completely empty despite the channels having many new videos, so I had to drop and re-add all of my subs to fix the feed.
I take solace in the fact that this most recent forced integration and re-purposing of G+ posts has been an unmitigated disaster.
It's very entertaining to see videos a few years old just FULL of G+ Posts, not Youtube Comments, from people who don't even realize those posts were public years ago. And now they're getting tons of attention of G+ posts through the Youtube website from mean and vicious Youtube commenters.
It's basically the exact opposite of what Google used to stand for online, with regards to privacy, safety and respect for users.
