Relevant Log Outputs

no error or message showing up on the log when i sort inventory.

I went to the inventory sorter mod and it seems that in the bugs items disappear when they are stacked, maybe sorting in curios also makes the items disappear. idk..

espacially this one talking about curios

Since this affects more mods than just Curios, there's unlikely anything I can do and this must be addressed by Inventory Sorter.
