You saw the title, that's my question. I ask mainly because of all the skill rebalancing. I just made a character with Astrology, will installing YHTNTEP mess up that game?
Your skills might be a bit messed up (like having double the skills on your bar for some reason) but it shouldn't crash or anything. That said, we can't guarantee it.
yeah it swapped out meatshield and the zombi summoning one for me yesterday. Not really complaining though since they make a nice distraction to chug down a potion or two.
