Cat Mail Co. Patch Note #3 Improves Parcels, Saves, and Lobbies

Cat Mail Co.'s third post-release patch adds storage tags and a clearing effect while making late-stage piles empty faster. It also reorganizes save slots and fixes parcel behavior, old demo saves, lobby re-hosting, localization, and visual effects.

At a glance

Adds more storage tags and a smoke effect when secondary piles are cleared.
Makes piles empty slightly faster during their final two levels.
Shows the most recently created save slot at the top of the list.
Fixes several parcel placement, stacking, and respawn problems.
Fixes old demo saves missing keys and lobbies breaking after leaving and re-hosting.

Player impact

Parcel handling and late-stage pile clearing should be less prone to interruptions, and hosts should be able to leave and re-host without breaking the lobby. Returning demo players may also recover the missing bright and dark keys in older saves.

Key changes

Patch Note #3 adds storage tags and a smoke effect for cleared secondary piles. It speeds up the final two pile levels, reverses save-slot ordering so the newest save appears first, and fixes old demo saves, several parcel problems, lobby re-hosting, localization, and minor visual effects.

What this means for players

Routine parcel work and save selection should be smoother, while a documented lobby failure and several progression-adjacent parcel issues are addressed. The patch may be especially relevant to players continuing from older demo saves.

Editorial context

Steam Update Radar assessment: this is a practical post-release stability and quality-of-life patch. The official post lists planned controller and input improvements separately; those future plans are not presented here as released features.
