@md5sha256 Do you allow me to includes your changes into my own fork and share them, in such a way that the jar file is downloadable and usable? Thanks!

[md5sha256]

Sure, although I would advise more extensive testing. This is currently on use on a production server and there do not seem to be issues.

Need this!

https://github.com/Aurelien30000/Inventory-Rollback/releases/tag/1.5.0 Feel free to use my own that includes this.

All the other changes I made are about code format and "logic", so don't worry ;)
