60420 Excavator sliding damage

Is this normal, or did I somehow mess up and put it together too tightly somewhere? Both the yellow and grey circles are being messed up by the rotation of the upper body. It's being played with (supervised) for a few minutes per week by my toddler, but I don't think he does anything too excessive with it. submitted by /u/VeneficusFerox [link] [comments]
