Could you fix this bug?

ERROR in

for object roomPusherDownNextObj:
Trying to use non-existing surface.

gml_Object_roomPusherDownNextObj_Step_0 (line -1)
Ah geez, that's a strange one. I am surprised it never came up. That object is responsible for all transitions to the next room going down.
I think I have rectified it. I have added a check in the step event that now checks to ensure that the surface actually exists before copying it.
sur_newroom = surface_create(guiWidth,guiHeight);
if (surface_exists( sur_newroom ))
{surface_copy(sur_newroom,0,0,application_surface);}
It shouldn't have needed this as the line right before the copy actually creates the surface it so my only guess is it was a frame rate thing. This change should fix the bug.
Thank you for letting me know!
