Game Version: 2.7.4511863
I’ve been playing Oranos online for a bit, and recently I noticed that researching Theia’s Lance of Stone no longer applies the tech to Contarius (the buff is missing in the unit information page, and the increase in damage isn’t applied).
To replicate this, I tested in an offline game against a CPU. I’ve attached two pictures.
This screenshot shows the Contarius with the Heavy upgrade (+2 damage).
It also shows Lance of Stone researched, but the upgrade not showing in the unit’s information panel, as well as the damage bonus not being applied to the Contarius Hack Damage.
