Low density structure can not be inserted into the rocket silo via inserters or shift-left-clicking, but can be dragged and dropped into the slot. This makes it impossible to automate rocket launches with the mod installed.

That's weird. I need to ask in the Discord or Forum because I have no clue why that is.

This can probably be worked around with something like this mod: https://mods.factorio.com/mod/RocketCargoInsertion

... Probably wouldn't let you ship LDSs, but at least you'd be able to automate launches again.

I'm considering removing LDS from the list if there comes no fix from Wube.

how about adding water as an ingredient for Cast LDS? in real life injection molding, parts aren't just allowed to slow cool, but Quenched by running cold water through channels in the molds.

For the moment I try to keep things simple. If the mod gets bigger, I might consider something for LDS.

Will be fixed in 1.1.0.
