When added via Twitch chat @exec@ will be changed to @exec_na@ in Deepbot
@exec@ has the potential to cause endless loops so the decision was made to change it to @exec_na@ so it could be reviewed by the streamer before being usable by chat. The streamer simply needs to change @exec_na@ back into @exec@ and the command will work as intended.
Sorry for an inconvenience caused,
