Inventory tick crash debugger triggered

Been experiencing semi-regular Assertion failed itemclass crashes for 3 days now. 
Error: appError called: Assertion failed: itemClass [File:C:\BuildAgent\work\b731a33f2a691e17\UE4\FactoryGame\Source\FactoryGame\Private\FGInventoryComponent.cpp] [Line: 1410]

They aren't tied to a specific area or action, sometimes the game runs for 2 hours before it happens, other times it crashes 3 minutes into loading the save. I finally had the inventory tick crash debugger trigger, so I would really appreciate some help.

I've tried the reduction of belt render distance, tried isolating areas I was working on when the crashing started using the interactive map tools, so far no luck.

Solution
I think I have removed the only two pairs I had setup like this, so far no crashes. I'll make this as resolved.

Resolution tl;dr

A merger to splitter pair had been set up with a direct connection (connection of 0 belts long) Inventory tick crash debugger triggered. This was possible due to some unintended behavior of AutoLink, Inventory tick crash debugger triggered this behaviour is prevented and should no longer cause 
Assertion failed Itemclass
 crashes.
