I have a strange issue in Cura (3.6.0) when trying to bridge a hole with single layer sacrificial bride: Cora slices 4 squares into the bridge that gets printed mid-air (which is of course not working).
Does anyone have an idea what is going wrong here (attached pictures):
layer 67 has the big hole
layer 68 is the sacrificial bridge (with the 4 squares)
layer 69 is the first layer of the smaller hole
