Help/Support Stack frames with no symbol names

Hello.

I am trying to hack an ios game with igg. The steps went mostly well.

However, as the image shows, there are stack frames that do not show symbol names. "And these offsets are also not found on Dnspy" (meaning they are missing when dumped with il2cppdumber. They do not seem to be in script.json or dump.cs).

And the game I am trying to hack has many functions that can be seen on dnspy, but they all seem inactive, and the real functions that are used for actual processing in the in-game scenes I need are hidden like that. So if I can somehow find the offsets with igg, I can rewrite them from the live offset patcher, but if that is difficult, I am stuck.

 

So I would like two pieces of advice.

1. What does it mean that there are no symbol names in the stack frames?

2. How can I deal with this problem?

Thank you.
