Flying vecicle like airplane. You need to achieve a certain speed for take off.
When try to run both AAI Programable vehicles and Raven, this happens:
aai-programable-vehicles__data-updates.lua:2...grammable-vehicles/prototypes/entity/entity-update.lua:90: attempt to index a field 'colision_box' (a nil value)
both work alone just fine
I have a in Erendel as well (https://forums.factorio.com/viewtopic.php?f=190&t=38475&p=356009#p356009)
Is the problem still relevant?
