I receive the error
W1517 player_input - no level!
at an unknown time for unkown reason.

player_input is a function of mine which let me 'create' objects.

It appears when I create more than 8 objects in my game, which (in code) are structures containing (and creating) various panels. Several functions are started at 'the same time' when I create one of these objects.
I don't receive any error when I place a wait(1) after a pan_create call. But that gives me other unwanted behaviour, so this workaround is no option for me.

Not loading any level here, I only do 2D.

What does this error mean and how is it usually solved?

Thanx, Joozey
