Campaign error (with Pic)

I am making a campaign, in it, my heros and heroin can walk through almost any doodad, it really sucks, I even turned collision on for all units. If any can look at the screenshot and tell me what trigger I entered that made it do this, or what I can do to fix it, please tell me.

I had that before too... if you use the enhanced world editor, it is possible units can walk through any doodad. I solved this by opening the w3m in the original editor, changing something random and saving again. When I launched it again it was solved. WARNING: The only thing is, the doodads I placed with the enhanced editor that should be impossible with the default editor disappeared or appeared like they would when you place them in the normal editor. So if using the enhanced world editor is not vital for your scenario, try saving it with the default editor. I guess doodads are unmasked in scenarios build with the enhanced editor.
And if you're already using the default editor, sorry, I've got no idea then ;)

I made it so far in the EWE but i have brought it into the normal world editor a few times. It didnt fix it then, i dont think it would fix it now.

yea i have the same problem... so if I save it w/ the regular WE, will my custom unit still have all the abilities i gave him using the EWE? (i didn't place any of the doodad's where they normally couldn't go...)
