Hi Alexis,
You can always download prior versions of LightBurn, see here: https://forum.lightburnsoftware.com/t/how-do-i-find-older-versions-of-lightburn/9104
It’s possible that the offset tool’s settings have changed from what you’re used to in your prior install of LightBurn - have you tried disabling/enabling Delete Original Objects and Optimize / Simplify results?
If you want to keep your file private, please email it to support@lightburnsoftware.com and put Colin in the subject line.
