UID is bad idea if you create instance by event cause you only know UID when you run app...
pick last created is bad idea cause i dont get linked to target instance
but when creating instance of object by event there is always auto - picking last created in the event
i can Make new Variable in object --> create new instance in event --> after this action edit in next action variable to give this instance custom UID --> make new event every tick condition and add another condition which is pick by comparision Myvariable == MyCustomUID
if anyone have better solution always be glad to read it
