Bones breaking for no reason?

[syn-prog]

Hello! So after some trial and error with no success, it appears as though the bones on my model like to break when I simply hit the "edit bones" button. If anyone can help me fix this I would be extremely grateful. Bellow are video examples of what happens:

Example One

Something I might've forgotten to mention on Discord is addon conflicts. Does it happen on a specific server? What addons are in there? You're not necessarily expected to know the latter but that is one thing we regularly need to check. Addons and servers make all sorts of code edits that may affect pac3 as a side effect.

I have a collection of all the addons on the server, but alas - the problem also occurs in singleplayer too. Loading the initial model works perfectly fine. HOWEVER, when I hit "clear" and then load it again or load another model, it will break the bones. I am not sure why
