CoSMOS Gamehacking Tool

What I did:
1. Set a breakpoint on a instruction in Disassembler View
2. Attach Debugger run to breakpoint and copy rsi address
3. Letting the process continue
4. Opening a new Structure Dissect Viewer and create a new structure with the address.
5. Game crashes

Error:
18:07:55 Cannot get items in class '', unknown error

The game is Valheim, Unity-based game.

In general is it okay to post bugs here or do you have another place where I can do this?

Thanks in advance

It is okay to post them here. Do you if RSI was a base address of a .NET class? Do you also know which class perhaps?

Yeah it was the ItemData class.
Btw is there another way to check the offsets for class fields?

Yes, open .NET Assembly Viewer, purple icon, when you are attached. Search for the class, right click on it and select 'Showstructure'
