Oh jeez...

I have the worst luck with my dolls.
Miyuki keeps falling over, and her legs are flippy and always pop out, and her arms do too. (she's my 50cm Obi)
Is the falling over a hip joint issue or is it something simple? And I think both arms have a crack in the joints. But I'm worried about the hip thing.

Hmmmm...Need more information.

Falling over...while standing? While being played with? When stored on a shelf? Is she wearing shoes, socks, other footwear? I does sound like you're not using the metal plate.

Legs flippy and popping out...At the hip? Knee? Ankle? Flippy and popping out at the same place or different places?

I store my girls (and guys) standing on a book shelf. They occasionally fall over usually because I bump the thing or I don't balance them well. They do fall over occasionally when I'm shooting MADh Vinyl mostly because they are precariously balanced. I have also found that shoes and boots that do not fit tightly seriously affect their ability to stand solidly. The magnets in Obitsu feet aren't strong enough to work effectively through many shoes. So if the shoes don't fit snugly and the feet can move around in the shoe, balance can be negatively impacted.

When she's just sitting down next to me she slowly goes onto her back, like her head weighs her down and she can't stay up.
The legs pop out of the hip a LOT so does the arms, right at shoulder part. And I lost the metal Plate in the move. ><

The legs shouldn't pop off like that and if they are so loose that the doll can't sit, they are not fully 'on' the joint in the first place. On the 60's there is a distinct 'pop' or 'click' that you feel when putting the legs on the doll. It does require some firmness to properly attack the legs. When I got my first one I though I would break her, but didn't. Once they 'click' into place, they should be much better. The only exception to that is if there is breakage or cracking of the hip balljoints.

The arms too are usually quite firm in the 50 once installed. I have on occasion thought I had put the arm in correctly only to have the post miss the hole for the shoulder joint, that results in very loose arms that fall off.Once again, unless there is something wrong with the jointing, the arms are normally reasonably firm in their position. there's no 'click' when putting the arms into place though. I have an older 60cm who arrived with lose arms, somehow either the socket for the post has become enlarged or the post was somehow reduced, either way the arms are lose, and I have to replace the ball joints at the top of the arm to fix it, sometime.

To me the symptoms you're describing sound like the joints need to be checked for cracks, and if there are none, then reassemble with care, and ensure each is properly 'seated'.

What Highlander says is true for the 50cm. One of the reasons this joint can be hard to make completely is that the vinyl of the abdomen gets pushed into this joint and prevents the two parts from mating completely.
Here's a look at the two parts at the leg/hip joint without the vinyl. You can see there is a circular groove around the peg of the waist part. The tube of the hip part needs to fit cleanly and completely into this groove in order for the joint to be made firm.

Frequently the abdomen vinyl is trimmed very tightly around the opening.

With the vinyl so close it is common to pull the edge of the vinyl in between the two parts as you push the two parts together. When this happens, the two parts do not mate completely and and if a big enough piece of vinyl is pulled in, the additional pressure can crack the outside ring of the waist part and/or the tube wall of the hip joint. The joint may seem firm at first but after a move or two the vinyl crushes and/or the hip joint part cracks and the unlocked leg becomes "swingy".

A preventative measure for this is to take a sharp xacto knife and trim the vinyl of the abdomen around this hole. The hole can be easily enlarged and is hidden by the leg parts so you don't have to worry about making the cut cosmetically perfect.

As for the shoulder joint, as Highlander stated, it is very easy to miss the receiving tube of the shoulder part.
Image

With all the adjustability of the 50cm shoulder part it is easy for the receiving tubes to become misaligned with the hole in the chest vinyl. It would be a worth removing the chest vinyl, "zeroing out" the articulations of the chest part and inspecting it for damage. It is not uncommon for the receiving tubes on the chest part to crack. These cracks can be very fine and hard to see. Inserting the shoulder part onto the tube can help make any cracks appear. These cracks can be repaired by applying super glue to the crack and clamping. If the cracks are too large replacement will be necessary.

I wish we could make an OBitsu repair compendium and put all of K2!s tutorials there. I know I'll need it in the future.

If I did, I'd have to title it, "Been there. Broke that."

Don't forget - "have the T-shirt." I think they do it on purpose!
