URock stuck while creating 2d grid

[Gittihubberbabba]

Hi all,
Sorry, I’m stuck on a second issue. The URock calculation always gets stuck during the creation of the 2D grid. I’ve tried running it with and without vegetation, using both the stable and latest versions of UMEP. I tested it on my Ryzen 9 laptop as well as on the Threadripper workstation at my university — both for about 24 hours. I Use Temurin 17.0.15+6 - 16.4.2025.
