Tyranid Campaign Bugs

At around turn 80, I encountered a bug where I couldn't devour any worlds. They get stuck on 2/3 turns. In addition, my ships no longer fully heal with the healing/troop replenishment structure.

Restarting did not resolve the issue and it appears the save is no longer any good.

has anyone encountered something similar? What can I add to help get this resolved?

Bump in hopes of a response. Would rather not have to ditch a turn 80 campaign. 😞
