I made one map with very big S3O objects:
Monopoly
in the last versions of TA Spring they disappear on the screen.
Only the shadows showed up.
If you zoom at the correct distance and move the screen a bit they will show up, but the whole monopoly fun is gone.
maybe its a bug in spring...
maybe its a bug in my map...
who knows the answer? you get real luck in future monopoly games :)
