This is the one that hurt the most. On Xbox consoles, players used "Test NAT Type" in network settings to lag themselves into a solo public lobby for safe cargo sales. Build 3274 for XB1 changed the session heartbeat timeout from 15 seconds to 5 seconds. If your NAT test cuts the connection for 10 seconds, the game now migrates you to a new solo session, but prevents any sell missions from starting. Result: You can still get solo lobbies, but business battles and high-demand bonuses are disabled.
Looking back from today’s perspective, Update 3274/3407 (111220) was a maintenance miracle disguised as a nuisance. grand theft auto v update 3274 3407 111220 patched
Before diving into the consequences, it is crucial to clarify the version confusion. Immediately after the update, players reported seeing two different client versions depending on their launcher: This is the one that hurt the most
Both builds share the same underlying executable date code: 111220 (suggesting a compile date of December 11, 2020? Or a build number? In Rockstar’s internal labeling, this is a legacy marker). The discrepancy caused an initial panic, with many assuming they had been locked out of cross-play or save transfers. In reality, 3274 and 3407 are byte-for-byte identical in function—the numbering difference arises from Rockstar’s branch-naming conventions across storefront Digital Rights Management (DRM) layers. Both builds share the same underlying executable date
What matters is not the number, but the fact that both represent the most aggressively anti-modding patch since the infamous 1.0.372.2 update of 2017.
This one hurt legitimate creators. The patch now rejects any custom .ytd (texture) or .ydr (model) file in online sessions, even if purely visual (e.g., a lore-friendly police skin). Previously, Rockstar only blocked script mods online. Now, any modified update.rpf triggers a “file mismatch” error (Rockstar error code 0xE019100A).
