This might actually be the way to have people see the inventorio inventory with trinkets by adding support for this mod! If support was made, this could fix the trinkets api issue with inventorio by having this mod instead! I've also posted this issue with the inventorio mod dev

For now, it looks like I shouldn't do anything on my end.

In depth, Trinkets mod is applying most important things in PlayerScreenHandler, which Inventorio mod isn't inhering in InventorioScreen, but creating its own InventorioScreenHandler which isn't on its own based on PlayerScreenHandler.

Never, should I describe code with my own words.

Simple speaking, if I in my mod implement this (trinkets support for inventorio), it would be much bigger mess, then it is now.

I will look into it.

For now, I can't do anything, because of this error, but after it is fixed I will work on it.
