I'm not sure if this issue stems from Tiny Progressions, Integrated Tunnels, or Storage Drawers but it seems to be caused by their interaction. I used 8 tier 8 cobblestone gens from Tiny Progressions with an item interface connected to each and an item exporter connected to a drawer controller. As soon as I connected the item exporter and placed a variable to only allow cobblestone to enter the drawer controller, the game crashed.

Here is the crash report:
