Twice now when trying to load into a SP world I get the following crash:

java.lang.IllegalArgumentException: Tried to create a genome for 'rootBees' from an invalid chromosome template. Missing chromosome 'speed'.
species: {computronics.speciesScummy, computronics.speciesScummy}
speed: null
lifespan: null
fertility: null
temperature_tolerance: null
nocturnal: null
humidity_tolerance: null
tolerant_flyer: null
cave_dwelling: null
flower_provider: {computronics.flowersSea, computronics.flowersSea}
flowering: null
territory: {Forestry.territoryAverage, Forestry.territoryAverage}
effect: {forestry.effectDrunkard, forestry.effectDrunkard}

It doesn't crash the entire game, and reloading in seems to work. I thought it might be because it was the "latest" forestry, but it's happened twice now, with two different versions. I can provide the world-save or entire instance if that would help.
