I loaded this plugin for temp VIP promo.  I added players such as this: addgroup 76561############ viptrial 7d.  I got confirmation, and the players were added to the group, only to have all the players removed a few hours later?  What gives?  The entries are in the config file at /data/timedpermissins.json, but they were taken out of the group for some reason.  Have I done something wrong?
