Recently in some games I noticed that when kubbs won't sit evenly that grass is being grabbed from out of bounds and put under the kubb to straighen it. Personally, I repositioned the grass under the kubb in a tournament this weekend to balance it. I didn't pull the grass, but tilted the kubb back and moved the grass to level the kubb. But after reading the rules, I'm not sure if that was legal. Is there any clarification on this rule that anyone can provide?
