In some random (new?) encounters, the animation completely freezes the game, stutters if you try to click, flail a bit, and then freeze again. Since the game has no save option, this means whenever this happens you have to start from the beginning. I wonder if this has something to do with the Tinker since it has only happened to me today, but in all three times I outfitted the ship with massive amount of trinkets.
Also Rosa doesn’t give you company when you already have 5 even if you have a side boat, so I think this should be mentioned in the book. Also I don’t find any entry on Specialize?
