Munchkin Swarm Broken (For Me)

Wrote some code and now when I try to load the stage, it hangs, indefinitely, regardless of the browser. I could reset my whole progress but for the sake of a legitimate bug, I will post here. Sorry for any inconvenience, new to the ropes.

Im not that much of a veteran in these terms, but could you post a screenshot of it failing, and check your JS console and copy-paste it here.
