These are controlled by the additional likes per day set of admin settings, and are still very much current: 
There are two messages you can receive about Likes - one is using all your daily allowance [1], and another for if you’re using them too quickly in a short space of time, which also has a cooldown period. I’m wondering if you triggered the second one instead of the first?
I’ve just had a quick blast on my test site with a TL2 test user just to be sure and it seems to be working as expected:
Just to add - The Out of Love badge is also granted daily, rather than triggered by a post action, so that may also account for a mismatch in when you got it versus how many Likes you had left for that day.
