Actually, long reach is working fine, but it's disabled because the version info in the info.json file says the mod is suited for 0.15.
I saw a discussion on reddit about this:
https://www.reddit.com/r/factorio/comments/7jl5fi/i_updated_squeak_through_and_long_reach_for_016/
As suggested there, a simple change to the info.json file resolves the issue:
{
"name": "long-reach",
"version": "0.0.8",
"title": "Long Reach",
"author": "James Aguilar",
"contact": "aguilar.james@gmail.com",
"homepage": "http://github.com/jaguilar",
"description": "You can reach anything you can see. You can build anywhere you can see.",
"factorio_version":"0.16",
"dependencies": ["base >= 0.13.0"]
}
And works OK for me, although I did only brief testing - in 0.16.6 (build 34439, win64). Not my mod, not my solution, but I thought to share this anyway because it's so simple...
