Switching from arco optics to holosight optics in the inventory after zooming in with the arco optics x12 leads to an instant crash, when zooming in with the holosight afterwards and a message saying "out of memory" will be shown on the desktop. There isn't a problem, when I zoom in with the red dot sight of the arco and then switch to the holosight in the inventory and zoom in with that then.
