Problem with Worldborder

Hi, I have a question, sry for my bad english …And indeed, after the last devkit update I have the problem that the Worldborder East and West no longer work, have already used new blocking volumes, in the corners everything works wonderfully but about 1/4 of the volume suddenly missing the collision … ,
anyone have any idea why that is? Collision stands on “inviInvis Wall”

Got it, i have copy the World from Ragnarok, and its work now^^
