A few days ago, my Trinket and Weapon slot upgrades both expired on the loading screen going down into the clockworks joining a friend. I had to leave, activate two more, reequip my weapons and join back, losing 10 CE in the process.
Give us an option to queue slot upgrades to be used immediately after the last one expires, or when we go into the clockworks. Also, make it remember what weapons were equipped.
A warning would had been better. That way I know my slot upgrade expires in 3 hours
