0.17: Can't add mod to existing game

[foophoof]

I tried adding long reach and loading my existing 0.17 game, but got this error:

The mod Long Reach caused a non-recoverable error.
Please report this error to the mod author.

Error while running event long-reach::on_init()
New value must be larger than or equal to: 0.000000
stack traceback:
	__long-reach__/control.lua:20: in function 'apply_long_reach_settings'
	__long-reach__/control.lua:2: in function <__long-reach__/control.lua:1>
stack traceback:
	[C]: in function '__newindex'
	__long-reach__/control.lua:20: in function 'apply_long_reach_settings'
	__long-reach__/control.lua:2: in function <__long-reach__/control.lua:1>

Creating a new game seems to work fine, so it seems to be an issue with adding the mod after creating the game.

I'm on Factorio 0.17.8 on Windows.

Here's my save file, to help reproduce (I have a few more mods that you may need to install, but I think the game should load without them): 0.17-game.zip
