Attempt to access nil value

Im playing via steam on windows 10, 64 bit pc, the issue is both on singleplayer and multiplayer (tried local only)

Im new to the beta branch, played all levels on the stable branch

Whenever playing on the molded grave biome whenever there is a spawn on the map (can be power but mostly mobs) the game crashes with this log:

[string "scripts/stategraphs/sg_prop_destructible.lua"]:89: attempt to call a nil value (method 'SpawnHitRubble')

It's impossible to pass this biome because its always crashing
