My counter is zero
When entering the event it says standing with no matches left.
Is the refresh timer bound to the start of my first standing match?
Same here. I made a thread in the bug subforum
At least one player reported having a full node restored
There is an ingame explanation.
Basically, it depends upon when you started playing the event, when the regeneration happens.
No explanation, what to do if you are unable to play due to RL.
