Hello,

 

I'm having issues with items not stacking in my server. I don't know if it's something a mod is causing, however I don't know if it absolutely is because it's happening across mods. I've attached a video of me attempting to stack torches, and some seeds from another mod called AE2. I've also listed the mods below of the mods that I use on the server.

 

Please let me know if any other information may be needed to diagnose.

 

Thank you.

Looks to me that one of the mods you have installed has set the max stack size of torches to 16.

This is not a vanilla or forge thing, you would need to start taking out mods and seeing which one will cause it.

It's rather simple, create a single player world in creative and try stacking things, remove a mod and try it again.

Rinse and repeat until you can stack again, and it is most likely the last one you removed.
