Anyone else having issues with this? I have the max possible boost time from research, but say I have 1d 12h of boost time left. I max it out which adds over a day and a few hours to that. I come back eight hours later and have only 1d 4h worth of boost time left, as if the boost all did not register.

Likewise, when I collect all continents, I may go from 5bc to 6bc. Then if I close the game, I will be back at 5bc.

Other items, collectibles, boosts etc. seem to be unaffected.

Edit #1 (Additional info): I can see the timer go up in all mines, and even "travel" to them and it will show them as being the boosted amount. Known for a fact that this happens when I leave the game while in a Lost Desert Mine. Has happened in others, but that is most recent occurrence.
