Large balls traveling under trough

At the REX competition (sorry that I keep bringing this up) the event organizer said that they did not manage to inflate the large balls by the required amount. Therefore the balls could, by some amount of pushing, travel underneath the trough.
Has anyone else experienced this issue?

Check the Q&A.

Karthik expressly said that the large balls are NOT supposed to be able to roll under the barrier. If they can, they need to be inflated more.

Yes.

The only reason that the large balls at the REX Hosts Toss Up event were able to fit slightly under the barrier was because (at least in my understanding) they didn’t have any sort of pump handy.
