+`BUGFIX: ReflectionService must always initialize <https://github.com/neos/flow-development-collection/pull/3360>`_
+-------------------------------------------------------------------------------------------------------------------
+
+The ReflectionService lazy loads reflection data from cache, but every method making use of the data needs to call initialize.
+This change adds missing calls that seem to never happen first in regular flow applications. Still better to prevent broken reflection in case we optimize other uses in the future.
