Im going to fucking murder the QA team if they don't stop sender bullshit issues!

QA: hey dev, there is an error with attached files.
Me: okay what's the issue?
QA: it's just a random file that gets attached. Can you fix it by the end of the sprint(tomorrow)?
Me: I need to investigate it a bit before I can tell you how long it will take, how can I reproduce it?
QA: idk, it was just there.
*several hours of testing later*
Me: I've tried to cause the 'issue' on my local server, the test server and the live server. But I haven't seen it and I have no clue what could cause it.
*30min. before I go home*
QA: dev you have to fix it before you go home! Because we have some other important issues you have to fix tomorrow!

FUCK YOU AND YOUR IMAGINARY ISSUES I'M GOING HOME
