This is a difficult one. As i have analysed a couple recordings i made.
Once we had 3 plants in the graveyard, with 3 zombies. But the plants lost there.
The other time the zombies had a single AI zombie just roaming the garden, and it counted as overtime.
As of now it looks completely broken.
I just want to note that this also happens on Solo Mode/Splitscreen so it's not only a multiplayer issue,
I also couldn't notice what the issue here is. It's possible that specific attacks suddenly make the counter reset to 0. I mostly notice that when a lot of plants and zombies are on the zone however.
