Cannot complete "Aplha 7"

[DylanDog]

Hello WZ community
I cannot understand why I cannot complete "ALPHA 7"
The objective is to establish a forward base in the Plateu: well I have done it but the mission does not end...
Any idea why?

Also the objective states:
"Supplemental
The synaptic link technology was at this location but was removed. Establish a forward base then continue research for the synaptic link"

but I have researched te synaptic link(I have already reasearch modules...).

did you destroy all enemies? as far as i remember you have to build the base and destroy every enemy unit (they attack you using some flying transports)

[DylanDog]

ok,, I`ll give it a try to see if there are still any enemies around...

It needs three defensive structures (hardpoints, bunkers, etc) to be considered a forward base, iirc.

Since we are on about how to finish levels. How do you complete Beta 9? As soon as I landed those VTOL's come and knock the breath out of you, despite getting reinforcements sent immediately I am complete wiped out even with tons of AA units and trucks in.
