When dropping items into the rocket silo's 'rocket inventory' slots using the 'drop item' key (default: z), the first press of 'z' puts two items into the inventory. Subsequent presses of 'z' add a single item. Expected behaviour is to always drop one item only.
Reproduce:
Build a rocket silo.
Open the rocket silo.
Grab any item from the character inventory (with at least 2 items in the stack).
Hover over an empty 'Rocket inventory' slot and press the "drop item" key once.

Re: [2.1.17] 'Drop item' key puts two items from stack into rocket inventory instead of one item
Hello and thank you for the report. I haven't been able to reproduce this, could you send a save file where this was happening to you?
Re: [2.1.17] 'Drop item' key puts two items from stack into rocket inventory instead of one item
Save file is attached, along with a video showing the behaviour.
In the video, the first item drop is a single presses of 'z'. The others are holding 'z' while dragging the cursor across cells. You can see it is somewhat inconsistent: moving fast enough drops one item only. Changing the hotkey for drop item from 'z' to something else doesn't change the behaviour.
Dropping items into other entities (e.g. chests, assemblers) works as expected.

Re: [2.1.17] 'Drop item' key puts two items from stack into rocket inventory instead of one item
I can reproduce this problem in version 2.1.17 as well, even experiencing a continuous stream of items being dropped.
It seems the detection method here is different from the boxes. With the boxes, holding down Z at a point will continuously drop items, but with the rocket silo, holding down Z only drops one item and then stops. I think the problem lies here.
