掲示板 Forums - broken forum bug

in a topic I recently created (tested when not logged in), I generated a 401 authorization error in my last forum post.

for example

if you click this link to forum post, you get sign in popup authorization issue: https://new.renshuu.org/forums/topics/16465/incorrect_kana_type_frequency_%28hiragana_vs_katakana%29

but if you remove the title of the post, you can access it like this: https://new.renshuu.org/forums...

I thought issue was caused by parentheses in the post title, but I tried to replicate it and could not reproduce the bug. sorry Michael this was not intentional I was just making a post and then this happened let me know and I can move it to a new thread. I am leaving the "broken post" up for now so maybe u can see what is triggering the bug.
