Look at the sticky pins on the right of the thread titles. For 3 of the threads it looks fine. For one of them, the thread title is too long and has been sent to a second row. Instead of the pin staying to the right of the thread title, it has been pushed off to a third row, while leaving the poster information on the fourth row.
Instead of changing 2 rows to 3 rows, it changed 2 rows to 4 rows. This should be fixed somehow.
