Astroneer has received Hotfix 2 for the MEGATECH update on Steam, addressing several community-reported bugs and quality of life issues while consoles wait for certification. The patch targets a nasty memory leak, a multiplayer cap, mission triggers, and the Megaprinter workflow.

“We do want to call out once again – We do not officially support mods, so if you have used them on any of your old saves, you are likely to crash. We are a small team and will not be able to fix that for you, so please don’t inundate the support line with reports on modded saves. We recommend installing fresh and starting a new save if you want to enjoy the content and use mods at your own risk! NOTE: This version will break crossplay compatibility for dedicated servers while we wait for this patch to pass certification on consoles. Steam players should be unaffected.”

Patch Notes – MEGATECH UPDATE HOTFIX 2

  • Fixed a memory leak associated with seeds from previous LTEs, because some of you had way too much Resipound.
  • Fixed Multiplayer limit bug, you are now allowed to have more than 3 friends.
  • Fixed the mission that triggers when you purchase the DLC, confirming your purchase.
  • Pardon Our Dust hat reward should trigger with the correct mission now
  • Fixed a bug where canisters on the Megaprinter needed to be set to output to start the print process. (DO NOT MOVE CANISTERS WHILE THE PRINT IS HAPPENING!)

The memory leak fix should reduce crashes and runaway memory use for players with older LTE seeds. The multiplayer cap change lifts the hard three friend limit, so larger friend groups can reconnect without server-side workarounds. The Megaprinter note is worth emphasizing. Players must set canisters to output and avoid moving them mid print or the job can fail.

Hotfix 1 and Hotfix 2 are live on Steam right now. Hotfix 1 and 2 will be deployed to consoles in the coming days while the developer waits for certification.

Comments and feedback are welcome, and readers can follow updates on X, Bluesky, and YouTube.
