Error loading a save with items from a mod that is disabled (Nanobots):

5467.681 Error MainLoop.cpp:1391: Exception at tick 22561680: The Item Network mod (0.8.4) caused a fatal error.
Please report this bug to the mod author.

Error while running event item-network::on_nth_tick(120)
Unknown item name: ammo-nano-constructors
stack traceback:
[C]: in function 'newindex'
__item-network/src/NetworkChest.lua:1032: in function <item-network/src/NetworkChest.lua:1021>

You could try editing the mod, .../src/NetworkChest.lua

Change line 1032 from
cb.parameters = params
to
if cb.parameters ~= nil and params ~= nil then
cb.parameters = params
end

See if that works.

Thank you. I'll try it as soon as I start using the mod.
