The issue is that non-space tier belt entities are not supposed to be placable on space flooring. Due to how Deadlock generates their entities, I need to forcefully modify their collision mask (vanilla tiers) to work correctly.
But since your mod doesn't do that, and since the latest patch doesn't allow for entities to have different collision masks that their downgrade, running the two mods together crashes.
To fix this, you can add a conditional override of your deadlock integration things under the condition that Space Exploration is on.
If mods["space-exploration"] then
data.raw[type][name].collision_mask = {"item-layer", "object-layer", "player-layer", "water-tile", space_collision_layer}
end
