Reporting a Bug:
Go to the sign in the warehouse and stand on the top side of the sign, facing south. You can collect the materials without having to fight the monster. However, you don't collect any materials (Unable to repair the window), if you move below it, you can trigger the monster to continue.
Also, if you click the sign twice, you will trigger an error that you are unable to find any instance for object index '100179' at qml_Object_obj_boards_sign_Step_0.
