Hello, 

I have read here: https://plariumsupport.zendesk.com/hc/en-us/articles/115002220929-I-stopped-receiving-Technology-Modules-every-day-  that modules stop being free after unlocking the basic technologies and the 7% bonus for uranium and titanium becomes active. 

I have checked that de 7% bonus is active and it is not. 

What are the basic technologies what could be an explanation for not the lack of the 7% bonus as stated in that page?

Hello!

Basic technologies do not require using Black Crystals to purchase the modules. The Black Crystals technologies are marked with the icon.

I believe you have to wait until the next server reset (0:00 UTC) for the boost to take effect.
