Hi, this mod causes this error when trying to use Squeak Through + Cargo Ships:

Error while loading entity prototype "boat" (cargo-wagon): Incorrect rolling stock bounding box and joint distance combination.There needs to be border at least 0.2 between the bounding box edge and joint.
Modifications: Cargo Ships › Squeak Through

The link to the bug thread in Cargo Ships is https://mods.factorio.com/mod/cargo-ships/discussion/5c15552ebe8766000d478068

I reported the bug on both Cargo Ships and Blueprintable Trains mod pages since I don't know which one is causing the issue.

Did you try disabling Blueprintable Trains and testing the other 2 mods?

Yes, disabling Blueprintable Trains fixes the error and the game works just fine with those 2 mods (+others).

Ok, I forgot to use table.deepcopy() when copying a bounding box. So the bounding box of a combinator and train were linked, resulting in an error when Squeak Through changed the combinator bounding box.

Fixed in version 0.16.18.

Awesome! It's working perfectly now, thanks for the quick turnaround!
