Troubleshooting

Problem	Why, and what to do
The designs aren't in the tattoo shop	Check that ensure zaiders_tattoos is in server.cfg and that the console shows it starting. Then follow your script's steps in Your tattoo script: some need its list. A player who was already in the server when the pack started must reconnect.
A design shows its code instead of its name	That script doesn't read the names the pack gives the game. Its list has the names: install it with zaiders_tattoos_install.
Other players don't see my tattoos	Check that OneSync is on (without it the console says so when the pack starts). With Config.DiagCommand = true, /zaiderstattoos shows whether your tattoos were sent and what the players around sent. See What other players see.
Other players see a tattoo lighter than I do	It was put on more than once, to darken it. Only ZAIDERS Appearance sends those layers; this pack shows each tattoo once.
Other players see wrong tattoos (from the base game or other packs)	Leave Config.FixTattooSort = true.
Another tattoo pack also shows its tattoos to other players	Turn one of the two off (here: Config.Sync = false), or both would put tattoos on the same players.
A design shows twice in the shop	Another resource with the same designs is running (an older copy of this pack). Leave only zaiders_tattoos.
zaiders_tattoos_install says it doesn't know the tattoo script	Your script reads the game's own tattoo shop, or isn't on the list. See Your tattoo script.

Still stuck?

Send us the console lines that mention zaiders_tattoos (from the server start) and which tattoo script you use.
