This has been happening to me as long as I can remember. If I leave my toon watching the progress of something being built when the timer reaches 0, I wouldn’t be able to print additional items. So I’d have to restart my client and that would usually fix things. Yesterday I started my quaters upgrade from 6 to 7. Taking 26 hours. My timer was coming up this morning, so I spent my time farming crusher hides in preparation for my next upgrade. I went to go take care of some personal business with 1 hour left on the timer. When I got back the screen said 0/0 seconds remaining, but then my quarters was still lv 6. Restarted client and… still lv 6… restarted again, tried a few different things to no avail. Wrote tech support about it so we’ll see I guess. Anyway. Y’all should know to never leave your toons watching the progress so this doesn’t happen to y’all. Happy hunting.
