eqFTP inactivity frustrations

[SheepDomination]

When I open a file via eqFTP for what it seems the first :30 minutes I'm able to save the file, followed by upload the file, after that amount of time of, basically inactivity, I have to download the file again, if there were changes made that were not uploaded prior to the inactivity, I have to download the file again and re-do those changes followed by uploading the file, quite frustrating, especially where you're in the groove of things.

Is there a way to bypass this quirk or is it completely non-related to eqFTP and rather the server to which eqFTP is fetching the file from ?
