I have been recently experiencing a few bugs:
Around 30-40% of times when I click right click on submit button and select open in new tab, The problem ID is not automatically filled. This being too often while solving from problem set is sometimes frustrating.
(It is recently happening in all ongoing contest) I opened dashboard, solved problems on different tab. I refresh the dashboard tab after some minutes and I get "?f0a28=2" this added in the URL. I refresh after sometime again. I get "?f0a28=x", x is the times I refreshed. After around x=4, I get error 403. The problem gets fixed when I remove "?f0a28=x" from URL and enter again.
Thanks.
