Player's auto sorting system ruins Raid Flares, any fix?

Basically I had a player complaining that NPC Raid Flares don't work and after an hour of troubleshooting, I figured out that if raid flares are placed into an automated sorting system, they are converted back into normal flares. So the player was just throwing normal flares on the ground and telling me that the plugin was broken. 

Obviously, the immediate fix for this was to keep the raid flares out of the sorting system and in a normal box but I was curious if there is anything else that can be done tp prevent this from happening?

the auto sorting system is that the convayer things or another plugin?

Just an automatic sorting system that the player built with in game industrial conveyors, splitters, combiners, etc. from the industrial automation update from several months ago.

i will half to look into that i would think they would just move the item instead of recreating it to move it 

We are noticing this happen too with normal stacking in inventory.
