I've noticed that some Forum Posts (specifically Burnie's latest update, "think before you delete" by Imperious118, and "Feature request: ability to search Community posts" by rezmanbrown" do not allow me to like the post. I can click the heart and it turns red, but if I refresh the page the heart turns clear again. Even after clicking the heart and turning it red, the cumulative total does not increase. Some posts this does work, and others it does not. I'm not sure what the difference is. It seems to work perfectly for all comments.
