Is the steam version up to date with the itch version?
because there's like a bug (I think) in the steam version where I can't start the fight with gravemaker paragon in the deepest part of Trannadar Depths.
There's a choice thing that asked if I want to fight it or not and I choose yes but nothing happens I choose no and nothing happens too.

Both versions have the bug. It'll be fixed in the next release, but if you really really really want to fight that one particular gravemarker:
This file should be placed in
Games\AdventureMode\Maps\Chapter 1\Trannadar Reserve\TrannadarReserveA\
(overwrite the existing file)
That should fix the bug and let you fight that gravemarker. There are lots of other bugfixes on the way but this patch may tide you over.
