I have a script that takes only 4 seconds to process in V 1.12.8, and more than 24+ hours when using V 1.13.0. All other variables are the same (computer, r and RStudio versions, dataset, etc.)

I am not a programmer, so I am not able to go through the code. Below you will find the sessionInfo() reg\rding thje environment AFTER changing back to V 1.12.8.
Please let me know whether I can be of any further help.
BTW, congratulations for this amazing gamecahnger package.
