Help! Pathfinding issue

I am using pathfinding for a character to follow the player and it works fine until i get to an obstacle...

so at a door i click to open the door (rotate sprite 90 degrees) and when i breach a wall (destroy wall).

The problem is when i do this and try to walk through the character stops following.

I make the character find path every 1 second so he keeps updating following the player, does anyone know how to fix this?

Thank you.

I guess you aren't updating your obstacles for the pathfinding..

For the object doing the pathfinding the wall is still there, there is no open door..

Ahh yes, now i feel stupid, Thank you.

If anyone else is wondering, all you have to do is regenerate pathfinding obstacle map when you open/destroy object.
