Bers asked me to post everything I wrote to him on the forum so here it is ...
Dear Bers, please can you always make hell pits visible so that when nearby people go to victory it is possible for the ones still playing to actually find them without having to clear half a map again.
This is where I had to start clearing from when the first person completed https://imgur.com/8XiLIKU
As you can see it isn't far from my dwelling at all being as Animated and Muscard Marsh are surrounded again and it has been solid mist since then.
Now I am one of the people that don't mind creature habitats as they don't cause problems if you keep on top of them but you can't when other people's victories can bury them under new mist and so you have to send your explorers out to clear areas which you have already cleared and maybe even more than once.
The Vile Groves and Breathing Glaciers aren't such a problem as they are nearer to home but Hell Pits are a long way away.
For the record last week I lost all my army except for 2 cats, 2 trebs and 2 mortars tackling one that had 26 dragons in it (managed to kill 19 of them though, wonder where the other 7 went) and that hell pit was from the week before that, found last weeks further on in the same direction.
Managed to find this week's in a different direction but thankfully with less dragons in ... there is just too much ground to cover when the mist comes down again so please make them visible as my 18 aerostats and 40 bards would really like a rest as they have definitely earned one.
