Loaded SKTileMap from scene disappear

Question

I'm trying to make a game and I need to render a tileMap that the player can move but also modify its size. First I created it programmatically, filled it randomly and it worked perfectly fine. As a result I designed a custom tileMap in the scene editor and I used it in code so that the player is able to move it or change its size and there I have a problem.

The tileMap is a 48x48 tileMap but if the intersection between the 24 and 25 column touch the left side of the screen, the whole tileMap (even the part on screen) disappear and if I bring it back on the screen (by selecting the invisible position where it was) and drag it back on the right it reappears.

The only solution that I found is to design the whole tileMap programmatically but this will take quite a long amount of time. Has anyone found how to tackle this issue ?

(changing shouldCullNonVisibleNodes and transparency has no effect)
