I suspended my client for about 5-10 minutes while I restarted my router after being up for ~380 hours and it went to 0mb/day and lost access to the quota again. I get that system is there so people aren't turning their clients on and off for the daily quota but it seems really strict for people running H@H on their home computers not being able to restart their computer for 5 minutes unless they want to wait another 24 hours to access the quota again. To clarify I didn't even turn H@H off. I just suspended it restarted my router and resumed it when my internet was back. The whole process took 5-10 minutes max.
Well, that's not intended, it looks like it can reset your client's timer when you go out of suspension. That wouldn't have happened if you shut your client down instead, but I'll make a note to correct that behavior.
Edit: This should now be fixed, grace behavior has been made identical to shutdown/restart.
