About fetching period

[ygecesefa]

Hi.Thank for your work.There is a problem with fetching.Because telegram some how renewing media referances by periods.So I got error then tg bypassing files upto new fetch.It set 2000 by default so it downloaded files for a little time about 200 file then bypassed up to 2000.We cannot roll back sync so it caused lots of missing file.I set fetch 50 but still causing missing file by this issue.Not much but files are important doent want to miss.

Can you add auto fetch messages when we got file refference expired error?Also can script bypass downloading if file already exist?So we can quickly sync all missing parts.And also topic support on channels on web page would be awsome.
