Poison will trigger on average every 10 days.
Poison cannot trigger within 3 days after the last poison.
Max duration until Poison WILL happen, hasn't really been set yet (maybe 20 days)
When the disaster triggers, will it come out of the blue or is it determined some time (2 days or so) in advance?
I think knowing the time in advance is better.
The day before the disaster (if known) would be interesting to play when all coins from center come out, and players
(especially those who can afford to hoard their coins) need some time to prepare for a longish playing session after the disaster.
Bots are always ready.
