If the person whose nickname needs to be changed has a role higher in the role list than the bot - including being the owner of the server - then the error message is messy. We should catch this error message and send an explanation about what can be done to fix it, e.g.:
Attempted to change nickname "Colin" to "(ST) Colin" but was unable. This is likely for one of these reasons:
Colin has a role that is higher in the role list than the Bot on the Clocktower role
Colin is the owner of the server
Bot on the Clocktower needs to be re-invited to the server to grant it nickname-changing permissions
This could be sent to the mover channel rather than being a private message
