What exactly is PushEvent()'s function?

[ethannnnnnn]

I was trying to fix a mod when I found that a function

PushEvent("itemlose")

was the issue. Upon removing this line from the code, the bug I was experiencing was fixed. However, I suspect that PushEvent tries to maintain continuity between server clients, which is why it appears to fix the issue for me, but perhaps the issue still persists (or is even worse?) for others if I remove this line.

Is my suspicion correct or would that be totally off base?
