Subject: [PATCH] Stop updating m_eventPtr on exit for reentry
The fix for recursive entity processing introduced a reenter flag that
returns the execution from the current function and switches to entity
processing.
The same fix also updates the m_eventPtr during this switch. However
this update changes the behaviour in certain cases as the older version
does not update the m_eventPtr while recursing into entity processing.
This commit removes the pointer update and restores the old behaviour.
