Help!! My custom skill 's tooltip extend has disappeared

Sometime my learn and extend tootip ( of my custom skill ) still exist , but few time later it's gone !!?

I don't know why it happened .

The thing that I edited is...
1. tooltip itself.
2. Stats - Item Ability (change to true) . <<< This one is neccessary for my work.
3. Stats - Levels ( change to 1 )
4. Art - Button Position - Normal X,Y
5. Stats - Race <<< Sometime Tooltip disappear when I change this ,but sometime its not .

Is anyone who experienced this problem ??

as far as I know, item abilities arent supposed to show tooltips adn what not, that's prolly the problem. I assume u made it a hero and item ability?

That 's rights . I changed that custom ability in Item ability to "true" , in order to add the fifth ability .

In the other word . It is " Permanent Abillity " , come with hero since players choose their hero and it's no need to learn and have only 1 level . I add it in X = 1 , Y = 1.

I planned to add it with other 4 hero skills . But I cannot add more than 4 skills . I have to add it in Normal Skill but the Normal Skill can add only Unit Abillity and Item Ability. That why I changed it to item abillity . ( "True" to both Hero and item ability .)

Any suggestion to add fifth ability (without spellbook) ? Or maybe I should reset my permanent ability to default when I need to change its tooltip .

Just uncheck hero ability and item ability and it will be a regular ability.

you mean that if i check hero and item ability to "false" it will turn into a Unit ability ??

OK, I will try . Thanks
