Marine and Submarine bug.

I made a custom map which is just the world map with a few new cities. I didn't touch the units. No one can use Marines in Subs. This also happens in other custom maps like Future Wars.

Error message:
the transport can only carry[unidentified unit:3]

Is marine transportable. is the submarine a transport

The submarine unit is bugged by default, you gotta give it the capability to carry marines manually.

Oh okay, thanks.

How do you do that, along with being able to carry other units ? the allow carry option makes it only carry one type of unit

Under map edit, you click on the units menu then click on the unit you want to modify. This will bring up a box with the unit info, such as stats, image, sound, defense bonuses, etc... Here you can make units transportable as well as define what kind of troops it can transport. Sounds like you need to make the transport able to transport all units that are transportable.
