Today Wikia has some bugs like this. I have seen in some other wikis, I found that the frames with <pre></pre> appears without codes. Another bug is table width. This is the Pig Dipper page. You can see the pigs column with is larger than normal and larger board size. I didn't edit the code for the table of this page. It's happen by itself. I hope this bug will be solved in a new few hours.
