Unable to join friends only multiplayer server

[mrkatananinja]

For 16+ hours of gameplay we did not run into any issues with connecting (Minus Factorissimo2 desync problems) Until today.

Today we got the error (only on my end) that mod startup settings were different. Not a big deal, lets just hit sync settings and oh... factorio crashes.
No worries, lets all of us hit reset on all of our settings and try to get on... same thing.
OH I KNOW! lets disable all of our mods and see that, well it kinda worked. So I was able to join other peoples base 0.15.5 servers, and even my friends without mods (different world of course).
Ok so lets try installing mods, nope doesn't work.

In total, I uninstalled Factorio 5 times on 2 different PC's
Uninstalled and reinstalled all of my mods multiple times,
waited till 15.6 came out and its still not working.

I'm currently running 0.15.x (.15.6 version) Base mod of Factorio with the mods:
Afraid of the dark v1.0.16
Air Filtering v0.5.0
Auto Deconstruct v0.1.8
Bottleneck v0.6.3
clock v0.15.0
EfficienSee v1.0.52
Electric Furnaces v2.2.1
Factorissimo2 v2.1.3
Flow control v3.0.1
Hacked Splitters v1.1.0
Long Reach v 0.0.8
Rail Tanker v1.4.1
Resource Spawner Overhaul v3.1.2
Squeak Through v1.1.7
Tree Collision v0.4.1
Warehousing Mod v0.0.12
Water well v1.0.17

As a reminder *I AM THE ONLY ONE GETTING THIS BUG* None of my friends are having the problem

I launch the game, go play>multiplayer>browse public games> search my friends name> join game> and it comes up with "Mod Settings Mismatch"

I hit yes, and it crashes my game.

This is an endless thing I've been trying to solve for 4 and a half fucking hours as of writing this post.

We've tried versions 0.15.4 - 0.15.6, reseting all settings on everyone's end and reinstalling mods on everyones end, and mine is the only one having the problem.
For the record, I have the same problem across different computers on the same network, so its not a specific PC problem. I am happy to give any additional feedback I can.

Thanks for your time

This should be fixed for the next version of 0.15.
