[0.17.79] Trees block biter bases on world generation

[White.Dragon]

Hello
Version: 0.17.79 (build 47865, win64)

Issue is related to generate biters bases (are not created) when you set a huge amount of trees (no free space).
In world generator set huge amount of trees. In preview of map you can see biter bases between trees, but after generate a map this bases not exist.
My guess is that trees overwrite or prevent creation of biter bases.
Issue occurs with and without mods.

This map exchange string should be able to help with reproduce this issue.

Thanks for the report. That's working as intended: biter bases won't generate if there's something else already generated on that location that they collide with. By turning trees that high it blocks them.

Thank you for explanation.
Please pay attention to one point - the difference between map preview and generated map (should be as similar as possible).
In my opinion this biter bases should not be shown on preview.

That issue is known and also not a bug.

I know this is an old report but it is still relevant in 1.0. I set biters to max and could not find many at all despite the generation preview showing a very high density. All I got were a few worms and tiny clusters of bases on ore patches.

If you declare this "not a bug", then there should be a note at higher tree settings in the preview window that the result may not be accurate.
I'm half okay with the idea, that trees are generated first and block enemy bases (In fact imho this is just a order of execution problem). It does not make sense but i am okay with it (if a note would be shown)

But leaving the preview window decoupled from the game feels completely wrong.

The "preview" has and will always be inaccurate; it's a preview - not the real thing.
