Weird issues with one side of connection after restart

[darkphoenix]

So just to put this out at the start: like half of what I'm using this bridge for is to get iMessage stuff into my Matrix system, because I like to keep my chat histories in one place if I'm going to look through them for something later. To this end, the backfilling is obviously quite useful, there's just one problem and another that sort of compounds: it seems the bridge is only able to send "my half" of things if given a token to use my account as the puppet, otherwise that half is just missing/it doesn't spawn a puppet for me. Is that intended or a bug? Either way, this is made considerably worse by the fact that for some reason the auth token for my account is forgotten every time the bridge restarts!
I can obviously copy paste in the token again, but by the time that message is processed, it has usually gotten through the full backfill and the chat log is quite incomplete. This bothers me quite a bit, is there a way to work around that, or is it a fixable problem?
