The crash is caused by Dimension Warp trying to use a LuaEntity that no longer exists.
The error points to:
__dimension-warp/scripts/scenario/lab_intro.lua:134
At that point, the mod loops through storage.intro_built_entities and calls .die() on each entity. The problem is that at least one of those entities has already been removed or destroyed, so Factorio marks it as invalid. Calling any LuaEntity function on an invalid entity causes this crash.
The safe fix is to check whether the entity is still valid before using it.
Change this:
for _, entity in pairs(storage.intro_built_entities) do
entity.die(game.forces['neutral'], nil)
end
To this:
for _, entity in pairs(storage.intro_built_entities) do
if entity and entity.valid then
entity.die(game.forces['neutral'], nil)
end
end
So basically: the mod is trying to kill/delete an entity that is already invalid. Adding if entity and entity.valid then before calling .die() should stop the crash without changing the mod’s logic.
