groups: [1, 17] # uses standard LZ map blocks or whatever blocks you decided were group 17
# blocks: [11, 12, 13] # overrides groups, so I commented it out if you copy/paste. UFO LZ only uses blocks number 11, 12, and 13 from the list
This is standard OXC behavior by the way. You might need to increase the map height in alienDeployments so that the UFO can be placed if the LZ isn't the same height as the ground. OXCE+ is necessary if you want to pick a single UFO by name or do some funkier stuff with stacking map blocks.
