Could someone pleast help with this unit question

i cant figure out why this unit can attack trees its only supoise to attack trees after it upgrades but it can attack them before and i dont know why

There's something wrong with the map; all the icons came up blank and abilities were set to "Unknown."

there is nothing wrong with the map the icons are custom so they wont show up but the icons shouldnt really mater the skills are custom as well i was just wondering if there was anything else wrong

THe icons should show up regardless of if they are custom or not. And none of the skills are there, WHICH I SAID, so I can't test them.

you dont need to test the skills the only thing that needs testing is the heros ability to hit trees i dont want it to do that that iconds arent in the map and the skills arent either

Why do you need others to do this? If he hits trees for you, it would hit them for anyone.

hmmm.... maybe so other people can see what mistakes hes done?:////

You dont get it... i dont want the unit to be able to attack trees its not supose to but it does anyway i want a way to prevent it from attacking trees

I want to know what to change to make the unit stop attacking trees
