Ok I can't remember if it were always like this. But I have been messing around with add-ons trying to get around the goza issue (you cant place add-ons on goza atm). So I placed a pentagram deed. Notice the object is directly centered over 4 teleport pads:
Then I went into custom mode and bounced back out. look where the pentagram is now:
It moved NW one tile. In fact I can bounce in and out of custom and the add-on will continue to creep NW untill it hits a wall. Then it re-deeds and goes in the moving crate. Has this always behaved like this?
