Do global unit and player variables cause leaks??

I'm guessing no, becuase they are global and always kept in reference.. but I just want to be reassured, or told correct answer.

yup your right. the in a sense leak, but not every time you use them, i guess only when they are created at the begining of the game. but forget all of that, i bet it was wrong. all i know is dont worry bout globals.
