Help MINECRAFT GLITCH

On my PS4, I've made a city and it was fine but when I left and opened the world IT HAD BLUE GRASS WITH BLACK LITTLE SQUARES AND CLEAR BLOCKS. Nobody else seems to know how to fix it? Has this happened to anyone before?

Minecraft PS3 turned back to trial mode?

I've had the full version of Minecraft for my PS3 for about 3 years. Then, this morning, when my cousin was playing, it somewhat put Minecraft back into the trial version. The game won't let us access our worlds, and we can only play the tutorial. Every time we try to get the full game, it says "An Ethernet cable is no connected."
We haven't been able to figure out what to do.

Minecraft PS4 not letting me place blocks in certain areas

I have recently made a Minecraft creative world. On the PS4 Minecraft console edition and it is my favorite world. Meaning I build on it constantly and always reaching the animal spawn limit and stuff like that. At the beginning I made a piston powered color changing Beacon. I bet you have seen a few of those before. Recently I was looking at it and saw it wasn't changing as many colors as before. I go in to wear all of the glass gets pushed by the Pistons and see Pistons are broken and glass not there. Like any normal person I think someone griefed my beacon so I go to fix it. But in the spots where it was missing I was not allowed to place blocks. I could place blocks everywhere else but not those certain spots. I'm then a very confused and almost rage because it is one of the first things I ever built and it was so cool. I have looked up trying to find answers but nothing came to my arrival. Most things were talking about how they were not allowed to place blocks in large chunks of area. But I was only not allowed to place blocks in certain blocks. I was also trying to make another one on top of it but was not allowed to place a lever in three spots and only one. I even tried exiting the game and going back in but nothing changed. All of this stuff is quite new to me because I have never had this happen in any of my other Minecraft worlds. Is it possibly due to the amount of items in my world. Or just a simple bug that will annoy me forever. Answer would be very nice thank you.

Shall I sell my PS4? And if I should how much?

Basically, it's a real big distraction at the current moment and I don't know if it's worth selling. Please help. If I do go on it I spend hours on it. It's a glacier white 500GB PS4 with original controller all cables no box. Disc version on FIFA 16, Far Cry 4, COD AW, GTA 5, COD IW and MWR. Downloaded games are Minecraft, COD BO3, Last of us remastered so 9 games in total. I also have rocket league (10 games). How much would this sell for? Everything works and is in top shape

Why can some people watch the same movies over and over again without getting bored, and why can't others?

I'm 15 and I know that for me, I can watch almost any movie multiple times a day without getting bored with it. For example, The Hunger Games (all movies). Any movie of the series I can watch it, restart it, watch it again, and repeat the process. Same with Divergent movies, Maze Runner, Tammy, Krampus, (just a few of many). It's starting to become an issue because my family is starting to get sick of the movies I watch. It's at the point where I only watch certain movies when nobody is home, and I change it whenever I think someone is coming. The same goes for video games. I have about 3 games: Sims 3 (PC), Skyrim (PlayStation), and Minecraft (Playstation) after I lost all mine while moving a couple years back. I've played all these games constantly for 5 years and still play them a lot. Especially with Skyrim. I only play Guilds, then I'll restart and do it again. Over and over. I actually will probably restart tonight. And watch Hunger Games again.

I tell everyone that it's because there's always a new point of view of things everytime you see or play it but that excuse is getting old. Is there just something about movies and games that let you watch and play them hundreds of times with no boredom? I have ADHD but I doubt that has anything to do with it. Does anyone else do this?

Why did games that require Ps Plus to play multiplayer, not need Ps Plus anymore to go multiplayer?

I remember when i got my first PS4 on Christmas and got Dragon Age: Inquisition, Minecraft, and GTA V. When i was eager to go multiplayer Ps Plus hit me in the face with its pay 2 play bs. So i have been playing free to play games for 8 months, as my mother did not want to get me a subscription. Yesterday i hopped onto Dragon Age: inquisition, i go to multiplayer and it actually worked, no Ps Plus message came up or anything. I did the same for GTA V and it also worked. I haven't tried Uncharted 4 yet. But i really want to know why this happened.
