Floor component seems to not run at Zombie solver (K2)

I want to use Floor component at Zombie solver.
But, error occurred.
Is it K2’s bug ??

Yes - this is a bug. I wasn’t aware of it, thanks for letting me know - I’ll get it fixed for the next release.
For now though, you can use this alternative Floor goal:
FloorGoal.gh (4.9 KB)
(You’ll need to set the assembly reference to the location the KangarooSolver.dll file on your computer)
