Tank riders present but can't be chosen

Greetings to the developers!

Good to see you've made EF compatible with 1.700 patch  :)

I installed the EF  1.800 and the 1.801 patch so it should have been  ok.

However,when I had one game today as Soviets (breakthrough doctrine or whatever it is called)I noticed that the Tank riders are still present as the 2nd option on the right side of the doctrine tech tree.

I know you've highlighted that they were removed,but why can't I see the change?

What is the problem?

The Tank Riders are gone, but now you can load any infantry onto a tank to shoot off of. :)

The ability now gives your infantry a chance to ride a T34 and in the same time gives to your light and medium tanks the flank speed ability.
