Neos Update 2.1.6: Empty sitetree and no content

Hey guys,

I have updated my Neos Instance from 2.1.5 to 2.1.6. Now my sitetree ist empty and I got a lot of Node Errors on my homepage :frowning:

I have tried:
./flow node:repair
(I got: Could not find any site nodes in “/sites” root node)

Call to a member function willChildNodeBeAutoCreated() on a non-object in /var/www/myproject/Data/Temporary/Development/Cache/Code/Flow_Object_Classes/TYPO3_TYPO3CR_Domain_Model_Node.php on line 501

I have also tried ./flow flow:cache:flush --force, doctrine:migrate and doctrine:update

Can you help me?
