Problems after pull/1319 #1332

After upgrading from 2.1RC4 to 2.1 got some problems with my projects.
First i have application-specific errors - empty collections after SQL-query. This error produces only after cache clearing on second page updating.
Second - number SQL-queries is bigger than in previous versions on some page.
Im use discovered reflections with MySQL/InnoDB.

This is query plan for Nette 2.1RC4
