On PC, with an R7 1700 and 1080ti, Windows 10 Pro 1803. I've been having an issue with the Taken Gun working correctly. Last night on Vault the following happened, if I picked up the Taken Gun and ran back to the correct plate and used the grenade ability nothing would happen. The Taken Gun would despawn but it would not key into the plate. Conversely if I used the Taken Gun on the wrong plate it would function as expected and kill me. Eventually we isolated the issue and I cycled off of running and we completed. Tonight we attempted Riven, the same issue was present with using the Taken Gun to cleanse the Symbols. If used on the correct Symbol it would simply despawn, we would not wipe from the lack of cleanse but it would not count towards activating the lift. Using the ability on the wrong symbol still resulted in a death. At the wipe screen it shows that I have 0 Symbols Cleansed. While discussing the issue with clan mates after we aborted our Riven attempt, I recalled the same issue happening when we first attempted Morgeth with the Taken Gun's grenade ability once not allowing me to claim Taken Strength and Free a trapped teammate. To summarize the effects are as follows: Morgeth, Grenade Ability has no observable function, triggering it does not free a player or claim Taken Strength from them the Taken Gun then disappears. Vault, When triggering the Grenade ability on the [i]correct[/i] plate, the plate is not cleansed, the Taken Gun despawns. When triggering the ability on the [i]incorrect[/i] plate, I still die and the Taken Gun despawns. Riven, Same as above, when triggered on the [i]correct[/i] symbol we don't wipe from the Cleanse mechanic but the lift does not activate. Also as above on the [i]incorrect[/i] symbol activating the Grenade ability still kills me and despawns the Taken Gun. I've tried changing my emblem in case there were any issued like present with the crystals on Shuro Chi and that did not resolve it. I've restarted the game and PC between all of those separate sessions and done a scan and fix, nothing was found by the scan and fix and the issue still seems to persist.
