Attempted to upgrade a lower-level Titan armor chest piece (The Plate of Transcendence) at 1600 power level with an 1810 power level Titan chest armor piece. It took my upgrade module and my 1810 armor piece but did not upgrade the Titan Power of Transcendence armor piece. Tried a Titan 1600 power level leg piece (Greaves of the Great Hunt) to a Titan 1810 power level leg piece with the same outcome. Both the Titan chest and leg piece show infinite power limit. Tried exiting game and changing character, but nothing changed. Afraid to try again and lose more hard-earned resources.
