Well not sure if it counts as big but its big to me okay?? So the tab on your profile where you can see your own forum posts, the titles when clicked do not send you to your post it gives you an error making it impossible to see the post.
for example: (it wouldnt let me upload images for some reason which may be another bug but no clue)
i think certain images have trouble uploading. not sure what thats about but usually the post thing happens to me too! the post is Still up you just have to access it differently whether through finding it on the recent posts page or notifacations. i think it fixes itself after a while so try again mayybee ?
