Well, that was intense. Got late to the party and pool stuck at me having 96 pending coins, then re-launch and now diff seems bit too high for my poor single card.
With block time 30 min (or is it stuck again?), at the moment i have no intention waiting 1800 minutes just to see if pending balance will go up, or we have another relaunch.
For people asking about pending=0, in previous posts it was mentioned about 40-60 minutes, but pending is calculated after 60 blocks confirmation, if block time is 1 minute then it's 60 minutes, if block time is 30 minutes then it would be 30 min * 60 blocks for your pending balance to update.
I may get back in few days when things are less 'intense'
