It's been resolved.
Turns out you don't need to specify hatch at all, just station or surface!

If spaceship to surface:

local multi_pod_destination = nil
if pod.cargo_pod_destination["type"] == defines.cargo_destination.station then
multi_pod_destination = {
type = defines.cargo_destination ...

As you can see in the picture, the cargo is clearly "not reseved", but the next step of the game is to report an error that it's already reseved. Why?
Or is there a better way to launch a rocket (only need space platform -> surface)?

Key Code:

---- in function Public.examine_cargo_pods(platform ...

I think this is most likely caused by Chinese (non-ascii characters). Because I tested all three blueprints with the name [1] [test1] [test+icon] and none of them crashed.

like this, I put "铺网格专用" blueprint book into recycler, and game crashed.

As the title says, my friend doesn't know how to delete the blueprints directly, so he puts the blueprint book in the recycler and then the game crashes directly. Please fix the problem as soon as possible. I have told him that blueprints can be removed by using the delete button to remove them.
