The runtime-api.json doesn't include Custom Input Events.
I did a search for selected_prototype in the api doc and only usage was as part of the LuaCustomInputPrototype

The link to Event Filters on the latest API home page is broken.

Autoplace specifiation peak documentation doesn't list the dimension attributes specifically, instead as `d_XXX`. This makes any machine reading of the API spec break, as it can't see that `temperature_optimal` is a valid attribute.

d_optimal :: double: d is the dimension name; this attribute ...

LuaSurface.can_place_entity() requires inner_name when the the entity you are trying to test place is an "entity-ghost". The docs don't mention it, but you get a missing key error.

Looks to be the same usage as the ...

Hit a similar sounding scenario where I use simple-entity-with-force as the player interaction entity, and a bunch of mod placed entities and mod global data around them.
Have to use the pre_build and match up positions and (hopefully correct) player surface against mod global data to detect a ...

This arose as a work around for this other bug: https://forums.factorio.com/viewtopic.php?f=7&t=93880

Basically I have a modded mine that makes everything in its radius inactive and indestructible. But other biters that were trying to path through these would often start attacking trees or player ...

Sorry I was quickly logging this as I came across a note I made when making a mod ages ago. I had assumed it was more common than it turns out.

The attached save reproduces the issue: aaa3.zip
The issue seems to be if the biter is already attacking the entity and then the entity becomes ...

If you set a tree's health to 0 to make it indestructible and can not be attacked, it will slowly regenerate health from 0.
0 would seem to have a special significance given it impacts biters and its not a reachable state in normal scenarios without the tree dieing. So I don't believe health should ...

Below indestructible is: LuaEntity.destructible = false
When biters try to path through indestructible entities they attack them, despite being able to do no damage. I believe the pathing biters are expected to treat an indestructible entity the same as an entity with its health set to 0 and know ...

I get a crash when connecting 2 custom rail signals with a circuit wire. I believe it is due to the rail signal only having 1 animation direction and 1 circuit_wire_connection_points and circuit_connector_sprites entry.
It only seems to happen on East/West rail signals and not North South rail ...

Trivial smoke generated via LuaSurface.create_trivial_smoke{} ignores the movement_slow_down_factor option when set to 1 in the trivial smoke prototype. This causes it to move around randomly. When this same trivial smoke is created via a trigger item it stays still.

My test trivial smoke example ...

The issue is the difference between a new BP being made and an existing BP having its contents re-selected.

On a new BP being selected the on_player_setup_blueprint event can be traced through to the player.blueprint_to_setup.get_blueprint_entities() correctly. With player.blueprint_to_setup.valid ...

Ah, that'd be why my searching around mod removal found nothing. Thanks for heads-up.

Yea that's exactly what it does in all other cases I've ever encountered in Factorio.
It should run a migration and remove all modded prototypes and instances and then load the map.

When Factorio ever errors it normally shows an error message and logs what went wrong. Standard error catching. So ...

Yes syncing the mods to the save is how I confirmed it worked earlier today. Technically some of the mods are sync newer than the save, but it still loads fine.
Only when no mods and the save is loaded does it crash.

The save is fine if loaded with all the mods. So no need for any extra effort thanks.
I only tried to remove the mods so I could test another mod against the map I'm general.

Loading the below linked save without any of the mods it expects causes the game to crash/close. There is no error captured on screen or in the logs.

No dump file is created.

This may be a silly question, but why doesn't the player.blueprint_to_setup object get reset to a readable state on the reselection of an area?
As an area of the map has been selected to load the blueprint from, is it not just some blueprint data like name, icons, includes(?) are pre-populated ...

sorry Dropbox didn't over write an old file with the same name. I assumed it would have, but didn't check for a conflict in fairness.
