"i gain lv from lv 1 to lv 4, but system gv me 1 wood only"
That's because triggerer use "hero level up" for a wood gaining, that's why this bug available.
How to fix:
i made another hero,stop his exp gaining.
Hero levelup - dummy hero again may collect exp. set his exp to the exp of "hero level up"
add wood same number as point stats of that dummy unit. set dummy unit point stats := 0 ,freeze again dummy exp gaining
