Oh this is so sad. Their CTF is one of well-organized and interesting CTFs in my opinion. Hope they hold it next year
Unfortunately, we decided NOT to hold TokyoWesterns CTF this year.

When debugging DLLs, I often need to go back and forth between @x64dbg and IDA. So far, here is the quickest way I have found to convert addresses. Is there a better one?
