Object reference not set to an instance of an object.

Hello! I am new to msstyles, and I am making a theme for fun. I tried to test my msstyles after making some changes and got this error:

What causes this error?

As there are hundreds of objects to look through, I would like to know if there is an easier way to find the cause of this error besides going through every object.

No, thats a bug. The message refers to some data objects in the program itself not existing anymore.
If you can reliably reproduce/trigger this bug. please open an issue with a description of how I can reproduce it myself.

I solved this a while ago, but I forgot to close this and give a solution.

I’ll open an issue later.

I cannot figure out a way to reproduce this issue so it may have been an outlier. If I remember correctly, it was caused by setting the IMAGEFILE property of a part to a large number like 9999. Since this isn't reproducible and the functionality is niche it's probably okay to leave it alone.
