Bug Description

Converting an aliases like any sword or any armor to plain any (sword|armor) causes skript to only cast the first element out of them in example sword returns wooden sword where armor returns leather helmet

Expected Behavior

Skript will properly return a random itemtype and not always use the same.

Steps to Reproduce

on load:
    loop 5 times:
        broadcast "Loop: %loop-counter%"
        set {_item} to any sword
        broadcast "Var: %plain {_item}%"
        broadcast "Aliases: %plain any sword%"

Errors or Screenshots

Other

This skript build is of master branch latest shortly after 2.7's full release Unsure about priority but I don't believe lowest is correct, as this effects somewhat commonly used aliases
