You need to update DT BOP, that error would have been fixed already. Anyway the latest will also crash due to some refactors made (I didn't realise this would cause issues with DT BOP), I've opened DynamicTreesTeam/DynamicTrees-BOP#68 to fix this.

ahh okay thanks for being so fast and responsive bro :)
