Macaroon and /in

[LS1S13]

I posted this in the Macaroon comments section before realizing I might get better responses here.

I'm having a problem with getting the /in command to work (provided by the addons InDemand or SlashIn), as in it does nothing at all even with those addons enabled. I've successfully narrowed it down to Macaroon causing the problem. If anyone has any idea on how to fix it I'd appreciate it.
