The free entry from liking Facebook page doesn't like me, i try to click the like but nothing happens.
Also silly me was watching stream from twitch, which doesn't count into watching, even after the long wait of follower actually registering, instead apparently you're supposed to hit stream throu this site.

Nevertheless, still loving the NMS stream.

also the buyable entry doesn't work properly, everytime i refresh the page it grants me another buy, yet it doesn't register it at all

Not sure if you got this resolved but a few things you could try if it hasn't fixed itself...

Log out of the website then back in.
Make sure you let pop-ups appear from this site. When you click the facebook or twitch button you have to look at the new windows and hit like or follow if you haven't. If you have then simply close the window and it should let you click the button for the extra entries.
Try a different browser. If your on Windows 10 don't use the built in, chrome seems to work pretty good.
As for the extra entry, make sure you have the needed points. Most times it is 1,000 for that extra entry.
