Bug on MS revenge (Divinity: Original Sin 2)

After talking with the Illness moved to the ship. It was a conversation with my companions (the Lowes IFAN without MESD, Sybil), then they went to the right and disappeared. To keep track of them is impossible, because it immediately starts a dialogue with the Illness and Gareth, however, clearly shows that they just disappear. In the end, there's the Red Prince, the Beast, FEIN and IFAN, but Sybil and Lowes as the wind blew. I tried to make the ship one and a Red Prince\Beast, the effect is the same - neither the Lowes nor Sybil. Now reinstall the game. Mods are not worth it, upgraded to the latest version, save overloaded repeatedly.
What could be wrong and how to fix it? Or to sit quietly and wait for the next update?
