I have no idea what can be done about this, but “lost connection to server” (not on my end) after almost a full fifteen minutes feels not-good when it drains time off your purchased booster.
Perhaps the actual time drain could occur post-match instead of constantly updating?
I may not be crafty enough to see where the abuse might occur since nothing is rewarded to the player unless the match is actually completed, thus leaving early could hardly be an issue.
And yes, not a major issue, but I doubt I am the only one running boosters during this weekend and it’s not exactly inspiring me to purchase more if I constantly run the risk of losing time. Then I’d rather buy six hours worth of reward credits straight up.
