When attempting to start a game the following error occurs:
The mod Module Inserter Simplified (1.1.3) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event ModuleInserterSimplified::on_init()
ModuleInserterSimplified/scripts/init-global.lua:57: bad argument #1 of 2 to 'pairs' (table expected, got nil)
stack traceback:
[C]: in function 'pairs'
ModuleInserterSimplified/scripts/init-global.lua:57: in function 'generate_allowed_in_entity'
ModuleInserterSimplified/scripts/init-global.lua:137: in function 'generate_global_data'
ModuleInserterSimplified/scripts/init-global.lua:187: in function <ModuleInserterSimplified/scripts/init-global.lua:186>

I can't reproduce this error. Could you provide your modlist?

What likely happens is that this mod gets confused by Sosciencity's Saplings being 'modules' without having an effect.

The error occurs when I try to load a game or creat a new one with this mod enabled: https://mods.factorio.com/mod/ModuleInserterSimplified
Disabling it the error does not occur.

But do you have any more mods installed? When I test it with Sosciencity, ModuleInserterSimplified and Editor Extensions, the game loads just fine.

The answer is for this ticket also:
