Not really a fix but more of a quality of life upgrade.
Write an approximate time window when the timer will expend on the placard. I know somebody here suggested to have that timer actually visible for everybody but I doubt they will do it because it will kill the point of having the timer in first place. But to have an approximate time, like from 10am to 2pm, will help people not spending whole day clicking while still regaining the reason why it got added in first place. You still will have that camp and RNG factor, it just won't be as major and long.
Strike me now.
