Hi,
you have replaced the MERGE flag in the loadscene call with KEEPPROGRESS in first call and with KEEPVIEW for the thumb calls!
and without that flags the elements will be not kept!
just add it again and it will work again
e.g. change it in your xml to:
KEEPPROGRESS => MERGE|KEEPPROGRESS
and
KEEPVIEW => MERGE|KEEPVIEW
best regards,
Klaus
