Completely sad ( not the game, me ) ?

Ok, so Ive had Minecraft for years. Im the guy who wrote the completely helpful review, TameTheDragon94, and Minecraft broke. Well, not the game. One of the worlds. I hope Mojang reads this. I need this fixed pronto. I dont know what I did. The only thing Ive done was import an new map, play it, and delete it. Then, I tried playing my best world, Utopia Village, and it just keeps crashing. I tried again today. Its almost like he crashes happen sooner every time. Well, another thing I did was Ive been using commands a lot lately. Like the potion effects and other things. Thats the only thing I know I did. I feel like I could cry. That world was my best one, the one Ive been working on for years. They need to make commands more stable. Like, I think it keeps crashing because of the potion effects plus the all entities command. Like, you can make you and all your entities run like the flash or jump like super man. DONT DO IT. Thats probably what did it. Mojang, if you read this, plz make commands more stable, particularly potion effects that are super high, and the @e ( all entitys ) switch. I still give a five star review because Minecraft is awesome, but I almost have a right mind to give 1 star because this is how much I am sad.

Ok, so with the new update it fixed itself ? but then stupid me went looking for a woodland mansion or the farlands or something and went far far away & the world crashed. Mojang, please read. You guys are awesome, but you need to add more stability to larger & more data used worlds that people want to go exploring. Please fix it.

PS- are you guys ever going to add armor stands, tipped arrows, jukeboxes, and all the cool ? stuff PC players have? I guess since yall finally added dyed beds, shulker boxes, magma & bone blocks, and terra-cotta yall will do it eventually.
