In this article it is told as to use things from an alpha and others without copying of sectors. Look video:
It is necessary to create simply Gib Object with Drop item property and to specify the necessary type of object. Red Potion and other, checked by Tekedon of a thing work the same as if I copied sectors from an alpha.
In addition, the type "61" drop "Bundle of TNT *" which in an alpha was responsible for "Stick of TNT". It seems that a monolith were going to add a stick and in final release because for Bundle the type "62" answers.
Distinctions in messages:
Type 61 = Picked up Bundle of TNT* (asterisk symbol)
Type 62 = Picked up Bundle of TNT (no astersk symbol)
