I already noticed this bug myself and will look into it. It should only happen if the grid (small or big) is below 20m in each direction.
I have to test if it happens on entering or on leaving and then find a way to prevent it.
If it happens on leaving then I will probably just block the pickup code for 1 or 2 seconds when the player is in a seat.

the brahmin jl-200 work platform ( https://steamhost.cn/steamcommunity_com/workshop/filedetails/?id=2880426342 ) if under the 20m regime, you could use it to test out if th ealterations work or not.
i also somehow managed to trigger a pickup upon entering the cockpit leaving me with a fiatn yellow glow the whole time i was in it.

would it be possible to remap the key so that the standard key to interact with inventorys, seats . . . isnt used?
standard for that is f or alternativly lmb for most stuff.
and yep i already managed to pickup a door with just a few blocks on it while trying to open the door . . . was a test for an emergency droppod with a passenegr seat.

So the check for inventories and terminals also doesn't work... I will have to look for a solution or change the interaction key to something else

Some Blocks (Box from Mod for example) have thier entire surface as an interactable surface and can't be picked up because of that.

Solved by changing the keybind from USE (F) to RELOAD (R)
