O yeah, the beneficial bugs still exist in the older version as well.
You would have to watch out for the non-beneficial bugs though, like the 1001 Lakes bug that can reset your guild progress. Then there's the one that gives Sarah a whopping +1000SP, which breaks her balance a bit. You could call that one beneficial though, if your goal is to break the game wide open. You can even trigger that bug twice if you really want to. There are other bugs as well, I'm sure.
I would love it if Indy were to someday release an age 16+ version of LF with all the bug fixes and everything, but add back in the few things that got cut. Don't know how practical that would ever be though. Probably best to just keep looking forward, rather than back.
