If an item with the same name as a fluid is removed from the game while an LTN station is sending the item signal out and there exists a content reader on the map outputting that signal then this mod will attempt to set the item signal on its combinator thingy and crash with the error
44.470 Error MainLoop.cpp:1284: Exception at tick 57083: The mod LTN Content Reader (1.0.2) caused a non-recoverable error.
Please report this error to the mod author.
Error while running event LTN_Content_Reader::on_tick (ID 0)
Unknown item name: water
stack traceback:
[C]: in function '__newindex'
__LTN_Content_Reader__/control.lua:139: in function 'Update_Combinator'
__LTN_Content_Reader__/control.lua:86: in function <__LTN_Content_Reader__/control.lua:78>
You can create this situation by installing the mod Attach Notes, connecting a constant combinator to a logistic train stop and setting the constant combinator to output a water item signal that the Attach Notes mod creates by running the following command while the cursor is hovering on the constant combinator
/c game.player.selected.get_control_behavior().set_signal(1, {signal={type="item",name="water"},count=1000})
Then place down a content reader that outputs this water item signal and disable the Attach Notes mod.
Here's a save game with this situation reproduced

If you load it with Attach Notes enabled it works fine, if you disable the Attach Notes mod and load this save then it crashes.
