3. Fixed a bug where previous costume-exclusive audio settings could cause the costume audio settings feature to malfunction in the new version.
4. Fixed a glitch where, after changing join permissions in a Custom Game, other rooms could use a duplicate name.
Maps and Modes
1. Fixed various terrain bugs that could trap heroes, cause clipping, or send you to strange places no hero should go.
Heroes
1. Blade’s Daywalker Double-Take: We’ve sharpened his technique as sometimes, quickly unleashing his Ultimate Ability after performing Daywalker Dash could cause the follow-up animation to overlap with the ultimate. Now Blade’s combos slice through the night, no more cinematic mix-ups!
2. Blade’s Stunned by the Sun: Using Daywalker Dash and Bloodline Awakening simultaneously and being stunned at the dash’s instant could cause Blade to bug out. Talk about a bad day for a daywalker! He’s now back to his unstoppable best, no more daylight drama.
3. Blade’s Dash of Discipline: The cleaving strike follow-up to Daywalker Dash didn’t correctly display the Slow effect on enemies. Now you’ll see his enemies feel the chill after every slash!
4. Hulk’s Gamma Portal Glitch: Transforming from Bruce Banner into Hero Hulk while going through a portal could warp his look more than a run-in with the Leader. Hulk’s textures now stay Hulked out!
5. Groot’s Blossoming Beautification: Groot’s Wild Wall wasn’t syncing up with some of his costume. Now, every bloom is Groot-approved, no matter the style!
6. Star-Lord’s Space Out: Placing a Network Leapspider teleport in certain tricky spots could send Star-Lord on an unintended trip outside the map! Peter Quill’s boots are back on solid ground, no more accidental galactic detours!
Console
1. Fixed a rare issue where XBOX users’ Lord proficiency avatars displayed incorrectly. Now your hero rep shines as it should!
