Проблемы с math.random

Добрый день. Проблемы с math.random(возможно что-то иное) в lua игры.

Если пробросить диапазон от 2 до 5 - math.random(2,5), почему то постоянно выпадает 2.
Перед функцией пытался вызывать math.randomseed(os.clock()), не помогло.

строки:
local ItemNum = math.random(2,5)
local ObjNum = math.random(2,5)
