I play with Dany. In our case we figured our the problem. During yesterday's game, which had obvious problems in coop, my progress is no longer aligned. In addition to this, the mini boss kinrangr in my session is bugged, it is visible and it is not possible to kill it. The system also allowed me to take an Antediluvian Chisel already acquired. As a summary I have the corrupted save and I cant do nothing to solve the problem.
