Do you have photos of your base?
Because for me it is not normal, I have seen photos of other receptions and the golden element where the piece is placed is not as high as mine, it must be lower than the plate "Nathan Drake" is at the same height as the element on the left representing a mountain.
It is normal that these 2 elements are at the same height to be able to maintain balance.
Mine not being aligned, the base does not have a good balance and moves when you press on it (I also think that it is because of this that the black plate with the pegs on which you fit the mast is not not straight)
Besides regarding this mast, I heated it and it finally came back in, but that's not why it holds well, it can come off at any time
Here is also a comparative photo with Justin's base (on the left) and mine to illustrate my points, The base must be like Justin's
