Problem with loading scene 0 in build

Hi all,
am having a bit of a weird problem.

Both my debug and my build load scene 0 fine on startup - however when going from another scene back to scene 0 my debug has no problems, but the build sits there and doesn’t do anything.

Anyone else dealt with a problem like this before?

cheers.

ok, fixed it - for some reason the build version didn’t like me using the WaitforSeconds() command.
