I had 50 prison tokens on my plot with no one trusted and I came back online and they were gone no one took them not my friend they are just gone.
Hey! The only way I could see this happening is: A) Someone stole them if they are trusted on your plot. (Do /p info trusted to see) B) You left them on the ground and they were stolen or cleared by clearlag. Or C) You left them somewhere else that you forgot and you thought it was your plot. Another thing is that maybe someone was ADDED on your plot and took them when you weren’t looking just before you logged out. Have any extra information? Let us know by replying
Goods don't just disappear, and it was most likely your friend or someone else swooped them up when you weren't looking. I'd try Sean's suggestions to see if any new information turns up; regardless, please be aware that griefing is allowed on Prison, so no punishment can be issued.
