unit range

when i made the spirit towers have 20000 range and i test it some how it gets changed to 700 in the game can someone tell me how to fix it?

and the spirit towers arnt custom units

there is a maximum ranges, you might be able to change it in gameplay constants,

You have to change the aquisition range to at least as much as the range.

I can only get aquisition range to be 1800, but the real range way over that.
