Bungie pushed Destiny 2 Update 9.5.5.5 on 10th March 2026, and this one is light on changes but not without consequence.
The single fix targets a bug where certain weapons weren't properly benefitting from their Weapon Foundry Sponsorships when those perks were active. If you've been running a Foundry-specific loadout and feeling like something was off, that wasn't in your head. Sponsorship bonuses are built into how those weapons are supposed to perform, so having them silently not apply could skew damage output, handling, or reload in ways that were hard to diagnose mid-session. Credit where it's due to Bungie for catching and shipping this quickly.
It's a surgical patch rather than a sweeping update, but if Foundry weapons are part of your current build, it's worth logging back in and seeing how they feel now. Full patch notes below.
General
- Fixed an issue where some weapons were not benefitting from their Weapon Foundry Sponsorships when active.
