Hello there, for the first comment the difference was that the 'old patch' had a different healing time on the vileplants compared to current patch. So it wasnt really fair to have them on a combined board. But if a vileplant takes about 3 seconds to heal instead of instantly that will mean you are on the current patch.

For the second comment I will ask in the discord if anyone has run the game on Xbox, to see if they found a different version of the final room etc and will get back to you if I can get an answer.

Hope this helps for now!
