Science XP Booster issue, definitely not 2 hours

So tried the xp booster yesterday from the science arcade machine, the 2 hour boost or at least that’s what it claims… less than 1 hour into use the boost disappeared. Is there underlying conditions to this boost that are not stated? Such as quitting the game and logging back in, timer decrease if playing with a friend, does dying affect the timer?

Don’t get me wrong the booster is great for leveling up a player but if it isn’t going to last the 2 hours because of a possible scenario listed above it would be nice to know ahead of time.

Thanks!

My xp boost last 2h and resets on every map reload, I can quit the game, turn of my console etc. it’s always active.

Possible is you got disconnected to shift then reconnected again so the boost dissappears.
