Crossplay Phase One was still in finishing work in September

Platforms: PCUpdated Evidence checked

The September 2026 State of the Game says the finishing touches were being put on Crossplay Phase One and submission was expected soon. This is a development status statement, not an announcement that crossplay is already live. Consult a later release announcement before using the September post as proof that a cross-platform connection should work. [1]

1.4.5.7 records a Last Prism crash fix

Platforms: PCUpdated Evidence checked

The 1.4.5.7 changelog includes a crash involving heavy use of the Last Prism. The report is attached to the PC release announcement; it should not be presented as proof that a particular console or mobile build already has the same fix. No precise reproduction threshold is supplied. [1]

1.4.5.7 fixes a multiplayer rope crash

Platforms: PCUpdated Evidence checked

The PC changelog fixes a crash caused by extending rope into unloaded chunks during multiplayer. Retain the unloaded-chunk condition when comparing a report. The note does not imply that all rope placement or every multiplayer disconnect shares this cause. [1]

Resolved

1.4.5.7 corrects an Aether generation case without Shimmer

Platforms: PCUpdated Evidence checked

Re-Logic records a fix for the Aether biome sometimes generating without Shimmer. The wording describes world generation; it does not explicitly promise to insert Shimmer retroactively into every previously generated affected world. Avoid destroying an existing world based on a recovery promise the announcement does not make. [1]
