PunFree Having editor crash issues

Ive been dealing with an issue in the game Im working on for the past few days where my game will crash while in editor, but not in a build. Ive been able to deal so far, as it only crashed when using PhotonNetwork.LeaveRoom, which I didnt need to call while testing in editor. Now however I am having the same crash issue whenever PhotonNetwork.Destroy is called. Unity crashes if I run in editor, regardless of whether the editor is the master client or not, but the build runs fine. Strangely too, when checking the builds logs for errors, I get none surrounding the objects in question being destroyed.

I feel like Im probably just missing something obvious, but any help that can be given would be greatly appreciated. Im running Unity 5.4.0f3, PUN free 1.73.
