SO as you can see in the picture all the buildables are like half the size they should be. I noticed when building beams the animation goes to the end of where the beam is supossed to be but the beam is a 10th of the size or smaller.
Other mods I have installed: Infinite nudge Smart Wireless lights Disco Trains

Hard to tell, but they look pretty normal sized to me - remember those walls are 4m tall and foundations are 8m wide, the scale often feels weird in Satisfactory
