Hi there!:)
My bf & I started playing ER with the seamless coop mod. It's been great until we updated to the latest version to be able to play the DLC too. Ever since every questline is scrambled (e.g.: Roderika is in two places at once). Also, Gideon continues saying progress-appropriate things but only if we are alone. If we are both in the Roundtable Hold, my bf gets the dialogue he says in the beginning of the game.
We played the whole game together, so the questlines are synchronised. We never progress without each other in the world. However, before we connect into the conjoined world, in the "single player" world, the questlines are normal and can be progressed from where we left off before the DLC additions.
Does anyone know what to do?
