Campaign proceeds to the final mission. (Battlefleet Gothic: Armada)

Hello! Faced the following problem. After the destruction of Abaddon system Taranto, the campaign moves on to the next story mission. So I have 89 in the course of the campaign! Searched for the solution, nothing found. Watched related to progress and all move to the mission after Tarantia goes from 31/32 of the turn... Maybe I'm something doing wrong somewhere stupid. But, in a word, I don't know how to fix this problem. Thank you!:)
