System.NullReferenceException: Object reference not set to an instance of an object.

[Csimbi]

Hello, I am not sure what to do with this error, so I am posting it here. Can issues like this be suppressed somehow as a workaround? You know, to get the rest of the code decompiled, by ignoring this error somehow and moving on to the rest? Thank you!

Steps to reproduce

1. Open Assembly-CSharp.dll
2. CTRL+S
3. Wait and observe error message.

Would you be able to provide the assembly in question, so we can take a look at the problem? Thanks!

I am not sure which game it was anymore - one week is a lot of time for me as I jump from game to game in days. Not sure how to check what games I added/removed that long ago. Sorry.
