Forum Is every update going to break a custom theme ?
 

I've got a custom theme installed on my vBulletin forum. It was coded for 4.0.0, was working perfectly and then 4.0.1 was released, I upgraded only to find that the theme was broken. I contacted my coder who "re-coded" the theme. Now I upgraded to 4.0.2 only to find the theme is broken again ! So now the theme has been re-re-coded. I honestly didn't expect this, there were no such problems in v3.

I'm no coder, but I need to know whether this is going to happen again and again as it's a big headache.
