Recipe Book Fatal Error on_load #157

Closed Zancmok closed 5 months ago

Zancmok commented 5 months ago

Im trying to load a game and got a critical error from the Recipe Book mod, here is the error: The mod Recipe Book (3.5.7) caused a non-recoverable error. Please report this error to the mod author.

Error while running event RecipeBook::on_load() RecipeBook/scripts/database/item.lua:17: attempt to index local 'group_data' (a nil value) stack traceback:

__RecipeBook__/scripts/database/item.lua:17: in function <__RecipeBook__/scripts/database/item.lua:7>
(...tail calls...)
__RecipeBook__/scripts/database.lua:69: in function 'build'
__RecipeBook__/control.lua:196: in function <__RecipeBook__/control.lua:191>

The save previously had the mod and it stopped working trought the playtrough, removing and reading the mods seems to fix the issue

The original file that gives the error: SpaceBlock[item=spaceblock-matter].zip

Did you change mod contents without changing mod versions?

yes

That's why. RB3 caches a ton of stuff outside of the global table and re-builds it during map load. If you change mod contents without changing a mod's version then it will have no way to tell that a configuration change is going to occur and so it attempts to load potentially invalid data.

RB4 will not have this issue.
