As discussed on Discord: please change the text allignment from top to centered for sign creation etc. in order to prevent text from moving up while autoscaling is enabled.

So I won't be able to change the alignment point, as that would change the position of text on every vehicle in every pack and make it wrong. But what I can do is when I auto-scale I can move the text down the same amount I scaled to have it stay centered. Would that work?

Yeah why not? As long as it stays centered... Or, like mentioned in Discord, just add more allignment options. Whatever is more comfortable for you.

Fixed in V20.4.0.
