The issue seems to have stemmed from Fire being stuck in a loop, constantly making requests to edit a channel, which resulted in it getting ratelimited. As far as I can tell, the edits were part of the permission role feature, so I've made a few changes to it which should a) help identify it and b) help resolve the issue
This feature is pretty old so it likely needs a rewrite to ensure things work smoothly, which has been added to my lengthy to-do list for Fire
For now, Fire is operational and should stay that way. If you encounter any issues, please report them in the Fire Discord (discord.gg/firebot)
