This season that I noticed this, all my matches have been in the evening after 21:00. I noticed that the "glitch" happened somewhere between 13:00 and 14:00 so in my case I know it is not before the match starts. It looked more like the timer was reset meaning 1 or 2 more hours to get the condition gain that I should have already gotten.
Nordeus please realize that we don't have time to calculate this every day every 3 hours.
