Maybe add a description to this?

That it only is set when a minable tile is placed and it is never deleted except manually with surface.set_hidden_tile()

Many hours spent figuring out a glitch in a map and it was a sneaky hidden ...

This prints "sand-1"
/c
p = game.player.position
game.surfaces.nauvis.set_tiles({{name = "sand-1", position = p}}, true)
game.surfaces.nauvis.set_tiles({{name = "concrete", position = p}}, true)
game.surfaces.nauvis.set_tiles({{name = "sand-2", position = p}}, true)
game.print(game.player.surface ...

Please do not remove the 'mineable wreckage' entity.
It will break many existing scenarios. Does not feel nice
Map creators like having a few "useless" entities.

"on_entity_damaged" is not a good option, it is too resource heavy for small tasks like this.
Would prefer to get the projectile somehow.

Can not find a way to detect when spidertron shoots a rocket.
For players "on_player_ammo_inventory_changed" works,
but a bit limited since it is called after a players ammo inventory was changed.

Adding an event "on_vehicle_ammo_inventory_changed" would work out,
since one could use "find_entities ...

Turning the notifications off is impractical.
Turning them on will lead to chat spam.

A small LTN toggle button in the top gui, displaying a scrollable text log when clicked, would solve this.
This would allow for even more detailed information, without spamming chat too much.

It seems, it is impossible to know who is changing permissions, if there are multiple admins in the same game.

This is a bit of an issue and could be solved by having an event.

will not reset the ongoing research progress of the player force.

Would expect it to reset everything, as it is described as "Reset everything." in the API

It does not seem to be possible to get the health of an entity, before it was damaged.
Adding final_damage_amount to the entity.health is only accurate if it's health is > 0.

If the entity.health is 0 then there is no way to get the health it had before the damage happened.
The only way around seem ...

Since 0.18, it seems that biters won't attack neutral entities like the rocks as well anymore.
A few special scenarios do not work as well anymore in 0.18.

The screenshots show a group of units that want to go to a location, occupied by rock entities.
But they keep being stuck running back and ...

Already patched! That was quick
Tested it and it works out fine.

Mining the tiles isn't possible now and one can still build other tiles over them.
But they do not get deleted underneath anymore,
so this is fine enough!!

Was more thinking of only setting it for specific tiles.
Maybe even for example certain areas of water tiles, that can not be landfilled.
Making all of them not mineable wasn't really my intention.
Maybe would write some custom script instead that uses the events.

Forces ?

LuaTile does not have that ability.

Teams? How does that work?

Players mine away or paint over the new colored concrete tiles that have been added recently.
If a custom map has a team spawn place, it can be easily removed or modified.

This could be solved by having the ability to set minable = false for a tile, protecting it from modifications.

Any new built farms do not work, with or without modules.
This happened since the update to 1.2.5
Game is currently online public, if a save file is needed.
Search for "comfy py alienlife" in the server browser to join.

Having simliar issue as crux042 wrote before.
New placed farms do not work after updating.

How does one create particles in 0.18 via LUA script?
Like "blood-particle", "branch-particle", "coal-particle" and such.

there is no way to do this properly, it seems, only found a way to keep track of some entities that were placed in the last x amount of ticks and compare them to the ones mined, but that is quite wonky
