tuna Sorry for the delay in response! Could you please try to run the following commands on Terminal while you open Spine and let us know the result?: pmset -g and pmset -g assertions.
These are helpful to check what applications prevent sleeping. For example, when I ran the above commands on my end, I got the following outputs:
misaki@MacBook-Pro ~ % pmset -g
System-wide power settings:
Currently in use:
Sleep On Power Button 1

I ran the commands while Spine was open, but there was no line which mentions Spine at all in the output results, so it appears that Spine does not affect sleeping. Please let us know the results on your end.
