Hey Rickje139, thanks for the report. I received the model from your game with ~20k parts welded together. Can you confirm that this specific model/usecase existed more than 2 months ago and was being used in your game? Just trying to confirm if the crash is due to any changes we made,.
I have received multiple reports where any assembly with more than 10.000 blocks crashes their game and this was one of them and used to work in the past.
