Just a Few Bugs: Help Please!

Hello, I would just like to report a few, very aggravating bugs in my game.

1. I cannot use any platforms whatsoever. Whenever I craft them, or take them from dungeons, they do not appear in my inventory ANYwhere; including the hotbar.

2. It happens quite often where I start my world up, spawn in my ship, attempt to beam down, and appear in my ship. No matter how many times I beam down, it would always place me in my ship again. I tried moving around my ship and hitting the button on the side of the screen, and it eventually worked, but it was a pain in the butt. Also, restarting the game a lot works too, but that takes longer.

3. A similar problem to #1, I cannot gather cobblestone. This is weird, because I can still use it, but I cannot see it, and it isn't even invisible in my inventory. This sucks, because I am reduced to only being able to build dirt and wooden houses, unless I collect buttloads of iron for metal walls.

4. Just general lag, whenever I beam down to a planet. It goes a way after a while, but it annoys me.

5. Similar to #4, whenever I beam down onto a new, fresh planet, I get HUGE amounts of lag. I'm guessing that this problem is already being worked on.

6. Whenever a monster kills me, it disappears. Not too important of a bug, though.

7. Wherever a dungeon is, it always create a patch of flat soil that goes on for about 500-600 blocks. This makes it really easy to detect when I am nearing a dungeon.

8. Silver spawns almost NOwhere on any planets. The largest clump I have found is 2 silver ore on the surface. None underground, either.

Sorry for the long list, but I believe these are all of the major bugs in my game. Please comment below if you have anything you would like to say. IN ADDITION... This isn't a bug, but how do you place background walls . I don't know how to.

 

You can place background walls my right clicking instead of left clicking.

 

Taco' I realise you say you've checked everywhere for those blocks, did you also notice/check the second tab within the inventory ?.
One looks like a backpack, the one next to it looks like a dirt block.

Can't say I've encountered the other bugs, teleportation to a planet is a bit of a wait as your ship needs time to position itself into place, assuming you're talking about going to a new planet.
Lag upon entering a planet/biome is expected on some systems, it's loading a new stage.

Only bug i've come across is once exiting the game, steam likes to tell everybody i'm still in it!.

Also, small flavor but pressing the arrow keys makes your character give face-emotes.
Especially funny when you're asleep in bed.
