T2 transports can only pick up 1 unit instead of 4

[rcstamat]

Description

T2 transporters, both Abductor and Skyhook, can only pick up 1 light unit now, instead of 4.

Expected Behaviour

All the small units should have a green circle around them showing the player that they are eligible for pick up and after clicking on them, they should be loaded in the transporter until the transporter reaches a max capacity of 4.

Actual Behaviour

The transporter doesn't pick up the unit
Units which should be available for pick don't get a green highlighted circle around them after pressing the load button, showing that they are available for pick up

Reproduction steps

1. Use the Load command to pick up 1 small unit in a t2 transporter (example: tick, pawn or construction turret)
2. Have more of the same small units available on the ground
3. Use the Load command to try to pick up more units in the transporter

Other

A couple of days before the introduction of the t1 heavy transporter I was using t2 transporters and this bug didn't exist. Sometimes in the past 10 days, this issue was introduced.

@Mitvit was this change intentional?

The multi-unit loading is currently so buggy that it should get improvements before being re-enabled.
