Hi, I'm not sure if this is a bug but I was confused for a while about it:

The "Spring Festival" thread said the last poster is Lokison, posted on February 6 this year. however, when I click into the thread it said that his/her post was posted in 2014. I'm sort of confused. And this user has not been online for 4 years and her/his last post was 7 years ago, so I don't know what is going on.

Edit: tried refreshing multiple times doesn't work, on chrome and macbook air newest version.

Oh more screenshots below:

I think someone gravedug that thread, then their reply to it got deleted, which is why it is showing the last poster, who posted in 2014.

Wait you can delete posts? :o or did the mods and admins delete it 

Staff (mods, admins) can delete I'm pretty sure.
