You'll need to send me your config file.

Changed Status from Pending to Work in Progress

Hi, I'm not opening a new ticket.
I think I have the same problem.

Okie, well still waiting on someone to send a config file..

Pretty sure I coded a fix, but I am not going to push an update out until someone sends me their bugged config to confirm. 

Was on 2.3.9, upped to 2.4.1 and got the issue.  Compared the config files, and they read as identical.  Attaching both for you.  The one listed as StackModifier1.json is the version after the upgrade was installed.

Okie so after inspecting the config file i see the problem. 

The item display name has changed and my code check is in the wrong order to fix it. I'll prepare a new update to fix this automatically or you can manually edit the config to resolve it.

Latest update should finally resolve all config problems with outdated configs. 
So pay attention to console output pls.
