Summary:
Mutant Battle Arena crashes immediatly when creating a new world

Impact:

This makes Mutant Battle Arena completely unplayable and as our most popular content will impact a lot of players. It cannot even be loaded. As a mature and stable piece of content it could affect many other pieces of content since it doesn't use any particular tech in unexpected ways.

Repro Steps:

Download Mutant Battle Arena! by Jigarbov Productions from the marketplace

The game immediately hard crashes. Assertions are off, so it does not appear to be an assert but something else.

The game should not crash

Regression Build:

Notes

This content was updates only a few months ago, so despite its age. It's also not certain how many other pieces of content are affected in this way, but hard crashes should be taken very seriously for mature & popular content like this.
