Initially, I had a save in story mode, and the cannon was there, but the day counter stopped at day 49. This annoyed me, so I decided to move to the infinite along with all my things. then one of two things: either I’m a fool, or the game is bugged, but in the end my things from the mailbox simply disappeared, along with the gravity gun. Now I’m wondering whether I need to create a new save in the story save and wait for this signal or whether it will appear in the endless one.

I would spawn things in in a sandbox save, then convert it to a normal save and use the mailbox
DO NOT convert your normal story mode save to sandbox because a few things get deleted permanently for some reason (like maxwell and some of the argemia plushies)
to change a save's gamemode go to votv's save directory (appdata>local>votv>saved>savegames) and change the prefixes of your saves to match the mode you want them in (a_ambient, s_story, b_sanbox, and I'm pretty sure i_ is endless and l_ is solar)
