Entity graphic issues

[Grundox]

So I created a spritesheet for a machine and wanted to take a look into the game but it was too big so I added

size = 0.5

and then I got an error saying that the Spritesheets width is not in the valid range (1-4096) but I didn't change anything there and even if it would just get smaller, right?
Later I discovered whenever I use a value below 1 I get that error and whenever I use a value above 1 the entity goes invisible. Why does this happen and how to fix it? Following is the code for the entity, the spritesheet and the error message.
Thanks for the help in advance

Size sets width and height at once. You're looking for scale, not size.
