Recreating a problem in the lab is not possible, and I need your help!

If recreating a problem in the lab is not possible, then it's high unlikely the problem can be solved in any time soon. It's just like if a surgeon wants to fix a patient, he can't just open the body and cut a random vessel or nerve, it could lead to catastrophic result.

All we can do is to speculate the cause, and try to recreate the problem in the lab. Alternatively, you can try to provide actionable information.
