As above, 2-3 times now Ive added markers and they have disappeared, not sure what I'm doing wrong

If you added them with API, then you need to re-create them every time server or plugin restarts

ok thank you 

Merged post

So, im new to all of this tbh, I dont really know what you mean. Would i have to save a copy of the Data file and then reuload it whenever the server restarts? Im kind of Noob XD

I have the same problem, if i add a marker with the chat command it will wipe the data file on server restart. On load/reload it does not delete the marker. Would it be possible to do so the plugin cannot change the data file by itself?

i dunno what i actually did but its not deleting now, I just add the markers and never reloaded the plugin and since then its stayed. not too sure on what happened tbh

yeah i had the same kind of thing, since then its been fine
