When this mod is enabled, Cargo Ships throws multiple errors on load:

Failed to load mods: cargo-ships/prototypes/ship_pump.lua:25: attempt to index field 'layers' (a nil value)
stack traceback:
cargo-ships/prototypes/ship_pump.lua:25: in main chunk
[C]: in function 'require'
cargo-ships/prototypes/entity.lua:4: in main chunk
[C]: in function 'require'
cargo-ships/data.lua:4: in main chunk

Disabling this mod resolves those errors.

Not sure if this is a you problem or a Cargo Ships problem, but these errors only arise when this mod is enabled.

I tried loading Cargo Ships and this Mod together.
Both seem to work fine, with no errors.

Tested with 1.0.8 Cargo Ships version.

Cargo Ships updated to 1.0.9 addressing the issue but that version does not seem to load for me.

This mod is a source of errors for https://mods.factorio.com/mod/squeak-through-2/discussion/671c70f6dc0b8de9590f7c2e. Disabling just this mod stops this error from happening.
