Topic: "new posts" subtitle near topic or category name

I found a stupid, annoying bug on the forum. I sometimes read NeverForum on a mobile phone. When I do this, I open all topics that have "new posts" subtitle. And when I am using a PC in the evening and open NeverForum, all these posts that I read on mobile are marked as unread so I must open them again to make them read.

I have fallen in love with Minecraft, but Neverball is still in my heart <3
