This crash happens somewhat consistently when I am in a lobby with a Grail Knight. I believe I have only seen it when a Grail Knight is in the game (Edit: This is not the case, see below). If I open the ‘Inventory’ menu, the crash occurs immediately when I press the ‘Spoils of War’ button. Curiously, opening ‘Spoils of War’ by interacting with the chest on the podium and bypassing the ‘Inventory’ menu seems to not cause this crash.
I have the ‘Armory’ mod enabled but I am not playing as GK when this has happened so I am not sure if that could still be the cause.
Note: I was experiencing a similar crash previously that didn’t rely on Grail Knight being in the game, but I believe it was related to having ‘Faster Chest Opening’ enabled in the ‘UI Tweaks’ mod. Disabling that setting seemed to resolve all of my crashing issues, except for when a Grail Knight is in the lobby.
Relevant crash report (I was on Kerillian with a Grail Knight in the lobby):
Edit to add:
It appears Grail Knight is not a necessity for this crash. Immediately after making the original post, I launched the game to open the chest and crashed using the same steps: Hit play, opened the Inventory, pressed ‘Spoils of War’ button, immediate crash to desktop. I was on Shade Kerillian in an empty lobby and I had a single Emperor’s Vault in my inventory. I do have ‘Armory’ mod active.
