I may or may not have had popping issues with this cube in the past...
But do you mean the cap on the x-center came off or it just flew straight out? Because I've had both happen (the pieces flying out also happens on the Vin 4x4), and I believe it mainly happens when you turn very rapidly and harshly. When my 5x5 became a 6x6 it was because of something like this, but the
edge was the piece that literally skipped over the center pieces and somehow ended up with three other edges...
I don't know much about better 5x5s (the only one I have is a non magnetic Meilong and the Vin, so I have no clue whether these issues occur on the Gan or MoYu cubes) but I really like this cube in general, just like its 4x4 counterpart, so I would just sacrifice a couple of pops for looser tensions

It also makes for
epic pictures when the cube goes boom
