There was a testing version that went into the default publishing branch, please don't save the game/delete any save/or try to change to a different save and restart steam to get the latest version, it should say v(0.27.4) or v(0.27.5). Sorry for that I'm looking into what happened.
UPDATE: I was testing a save to look at an specific crash, to do that I enable a check that loads a custom save file. My unity crashed after I had returned this check to normal and put it back as enabled, this caused the update to have this check on, I'm sorry for those who had their save affected by this, I will be more careful next time and double check this when Unity crashes or does something strange.
