APEX Crash Issues

Hi Folks,
We’re getting a set of errors with APEX cloth that are causing a crash. Here’s an example:

[2017.01.26-23.14.45:692] 0]LogApexClothingUtils:warning: Building adjacency information for a clothing section in skeletal mesh ‘/Blackclaw_Male/Buckskin-Armor-Set/buckskinArmor-kilt.buckskinArmor-kilt’. Please resave the asset.

The error only occurs when we make a development build, if we switch to shipping build the crash goes away, but shipping build breaks level streaming. For now we’ve removed APEX cloth from the flag assets, but what could be causing the issue? Any guess on what we could change to fix the issue? Or how it wants the asset “resaved”?
