Changes:

Completing the Vor's Prize quest missions will now mark the nodes they're on as completed, so that you don't have to backtrack and complete the nodes leading up to the Junction a second time before you can enter it. Anyone who is mid-quest after this Hotifx deploys will still have to backtrack. We now allow progress towards Junction tasks during the tutorial, and with this we also fixed Junction tasks not working during Quests. Swapped Nanospores for Salvage as a crafting requirement for Chroma Chassis, as players cannot acquire Nanospores until later in the game. Changed the Market 'Blueprint' Purchase option to read 'Purchase Blueprint'. Tweaked the difficulty of Spy missions. Rebalanced enemy levels on Pluto to follow the order of the mission nodes. You can now revisit Junctions, and see their new and improved diegetic menu! Junction battles now have different passive bonuses for players competing against Specters to make the fights more fair. The passive bonuses are: Refilling ammo on respawn. Passive energy regeneration.

Fixes:

Fixed an issue that would occur when Transmuting Mods where it appeared no Mods were consumed. This was a UI bug only, consumption was occurring as intended. Fixed an issue where there was no way to select multiple missions that all were occurring on the same node. Fixed Saryn Prime Systems Blueprint and Soma Prime Barrel duplicate rewards on Relics. Fixed the missing Nova Prime Neuroptics Blueprint, and added to a Relic reward table. Fixed an issue with mission rewards that occurred in groups of 5 (5 x Rare Fusion cores, for example) not rewarding properly. Fixed Clients not being given bonus Void Trace when other players choose their reward at the mission complete screen. Fixed the Landing Craft ramp closing on Warframes . Fixed missing UI information for the Stradavar's different fire modes in the Arsenal. Fixed an issue where the Void Relic screen was unusable on controllers. Fixed an issue when changing an audio device to a new device with different channels. Fixed an issue with Mods received as mission rewards not counting towards the "cCollect X mods" Junction task. Fixed issues with players on controllers being able to access the Pause menu in the Market. Fixed an issue with the new 30 Day Resource Booster charging and behaving the same as a 7 Day Booster. Fixed misleading information on the Resource Extractor Deployment UI in regions where they cannot be deployed. Fixed a secret button appearing on the Gear / Emote overlay. Fixed missing footstep sounds in Junctions. Fixed an issue with a Grineer Capture mission having a Corpus target. Fixed an issue with being unable to deploy Resource Extractors to Eris. Please note next Hotfix will come soon, and will fix a known issue with Alerts not properly labelling added Fusion Cores in the UI.
