Okay that's all well and good but where does it show your tech level?
Go into the system map and select the station which will show the facility effects including the current tech level, but TBH having everything represented by blue (for increase) or red (for decrease) chevrons without knowing how many levels a single chevron represents is counter intuitive.In my case I created a Coriolis that had an active shipyard until today.
As @Adamaira asked, where do I go to check my station's tech level and if needed, raise it?
Just my $0.02, but creating a Coriolis is a heavy lift, and I would hope that an active shipyard would be a baseline feature that would not require additional effort.
The information should be presented as numbers and not some system only the devs understand.
But for changing it, you should see the same information when you build new facilities, so blue chevrons are good, but red are bad and it's likely you need more then 7 to get a tech level of 35.
