Opacity does not respond to gyro sensor

If you set the opacity of an object to {sgx}*100 (or something similar) it generally breaks {sgx} entirely.
Examples:
Set the rotation of an object to {sgx}*100 = works
Set the opacity of an object to {sgx}*100 = doesn't work
Set the opacity AND rotation of an object to {sgx}*100 = neither work

Haven't tested other sensors. Thanks!
