It is because “tiles-fulgora.lua” performs a `table.deepcopy` on the “water-shallow” transitions, which also copies the “water-out-of-map” textures.
tiles-fulgora.lua:
Code: Select all
...
name = "oil-ocean-deep-2",
type = "tile",
order = "a[oil]-b[deep]",
subgroup = "fulgora-tiles",
...
...
transitions = table.deepcopy(data.raw.tile["water-shallow"].transitions),
transitions_between_transitions = table.deepcopy(data.raw.tile["water-shallow"].transitions_between_transitions),
...
