I am a Test engineer in a company. Recently, I caught a special bug. Here is the bug description.

As per my understanding, this is a critical bug. 

However, the problem is that this bug is only reproducible on that specific test environment. Development team is unable to reproduce that bug. After discussion between Dev team manager and my manager they decided to abandon the bug. 

This bug still bugs me and I feel like raising it to boss of my manager because it is a critical bug. What should I do? 

EDIT: The bug was in open state for two weeks before it was abandoned. Both Dev. and Test managers had thorough discussions on this particular bug. Dev team had no clue about how to fix this (It was not a simple fix). The bug was only reproducible in one particular env.
