I use this code to upgrade mirana abilities( in general ):

Code:
	if( ARROW:CanAbilityBeUpgraded() ) then
		BOT:ActionImmediate_LevelAbility( "mirana_arrow" );
	end

	if( LEAP:GetLevel() >= 1 and STARFALL:CanAbilityBeUpgraded() ) then
		BOT:ActionImmediate_LevelAbility( "mirana_starfall" );
	else
		BOT:ActionImmediate_LevelAbility( "mirana_leap" );
	end
i write this lines in AbilityLevelUpThink() function in file ability_item_usage_mirana but it seems this function does not triggered. in bot_mirana the function actionimmediate_... works fine but here , no ....
glad to read your suggestions and ideas...
thanks
