SH3004: A file the operation reads or writes can't be

Class: operation, exit code 1.

A file the operation reads (import's file, replay's record) or writes (a pack, new's files, playtest's history) couldn't be: it isn't there, a folder is in the way, or the system refused.

How to fix it. Check the path and the folder's permissions; the message ends with the system's own reason.

For example:

replay: error[SH3004]: missing.ron: No such file or directory (os error 2)
