If updating then
Recently, games like Counter Strike: Global Offensive, Team Fortress 2, and PAYDAY 2 are not downloading correctly.
What has happened, is that I start downloading or updating one of those 3 games.
Deleting an add-on removes any data associated with it, where disabling and re-enabling does not.
Please note: The fix does not apply to Firefox ESR or Firefox for Android.
What I found to be the problem was the formula and the fact that I surrounded numbers with quotes.
In Settings I had to change Automatic Update command to Full Calculate and then back again.I changed the setting as indicated above; but the auto-recalculate still did not work, and upon rechecking the "Calculation" option, found it had reset itself back to "Manual" all by itself.Three attempts later and it was still adamant it wanted to be "Manual" and nothing else.However, the download speed that it reaches suddenly decreases and eventually stops, leaving an "Update Required" message on the Downloads page.I've reinstalled Steam, done the "steam://flushconfig" trick, disabled any programs that would have interferred with Steam, reset my router, and some other possible solutions but nothing has worked.
