Tyr's Fall Scenario borked

when it is time to witness tyrs fall ,place the silver shard … enter and the game crashes

The scenario worked for me. However, when I had to retrieve his memory, the mobs were not attackable and the progress bar stuck at 9% until someone else started that phase. Then I was able to attack their mobs and progress my bar.
On stage 6, the vehicle abilities always flickered and reset the first time I pushed them, then had to push again to get them to work.
Other than those things, it was a great scenario and I was glad to play it.
