I think we can do like
```
logFile, err := os.Create(logDir(s.Id))
if err != nil {
    log.Println("Error creating log file")
    return
}
cmd.Stdout = logFile
cmd.Stdout = logFile
cmd.Run()
```
Where logdir is similar to worldDir- maybe something like `worlds/world-<num>/log.txt`?

That way we have logs when shit fans the hit.
