Scale Tool windows defaults to random percents when real-time drawings is enabled.
To recreate is problem: First enable Real-time drawing. Then draw a box. With the Scale Tool window open, uniform scale the box 400%. Duplicate that box by holding down OPTION key while click and dragging the box. Click on the second box and open the Scale Tool window: when I do this I no longer see 400% in the scale percentage, instead I find completely random numbers and sometimes it selects non-uniform. This gets annoying after a while.
Can also confirm. This is driving me absolutely insane.
