Sign Images disappear after a period of time? is there a fix?

They shouldnt dissapear unless you delete the sv.file or the map save

Yeah i saved the map and have not deleted the sv.file, but they turn blank after a period of time. 

Are the images unique per sign? If not, Rust will consider them the same sign and remove the duplicates.

No they are duplicates of the same sign.

If they are duplicates, that would cause the issue.

okay thanks
