I have noticed that a rotator acts like it does not have enough torque if it is placed on a build that is too heavy
This means that I cannot test weapons if I use a superheavy fuel tank for stability.
It even happens if the weight itself is NOT on the rotator, but on the platform the rotator is on.
An existing proof build is the TG-02 (quite long ago) which shows that even without an infinite fuel tank, but with legit fuel-holding fuselage, the glitch still happens.
So, I have ruled everything out except for creation total weight. Please fix!
@MrMecha luckily my mechs are never too heavy
