Flying vecicle like airplane. You need to achieve a certain speed for take off.
Mods introducing new content into the game.
Transportation of the player, be it vehicles or teleporters.
i have this problem in which the vaicle stays on the ground and never takes off, other mods that i have include AAI, alien biomes, aircraft mod and liftoff enhanced. do you know if it is from the mod itself or an issue created by another mod?
