So in page 209 of Transhuman it says:
Does this mean that Flexbots of Large+ size straight up loose the ability to reconfigure themselves? It says you can no longer do it rapidly, but what does rapidly mean? Do the adjustment times get multiples by a set number or something? Extremely large flexbots may be created, but the amount of fine control an individual ego has over the constituent modules diminishes the larger it gets. In particular, large flexbots lose the ability to rapidly reconfigure themselves with the shape adjusting enhancement.
