Gemling Legionaire Acendancy Class Not Working

Hi,

The Gemling Legionaire Acendancy class seems bugged. Specifically the passives Gem Studded and Integrated Efficiency. I tried using them and they made a bunch of my skills unusable. I could not make support gems to socket into a lot of my skills as they were all greyed out saying they could not be used, even the recommended ones. The skills affected were fragmentation rounds, high velocity rounds, armour piercing rounds, herald of thunder and shard scavenger.

Are you exceeding the stat requirements for your support gems?

At the top of the skills pane, the game shows your current number of socketed support gems and the maximum number you can socket, for each attribute. The capacity goes up by 1 for every 5 of the attribute you have--for example, with 15-19 Int, you can have 3 blue support gems socketed.
