Update 1.4.3580 fixes and wishing you a happy 2023!

Posted December 17th, 2022 by Tia Young

Various fixes, modder tools, remembering 2022 and onwards to 2023!

Hello, it’s Tia! I’m here to share a small update just before the holidays. ❄️️

Today’s update comes with a looong list of fixes. Loads of these were made with the help of our testers – a big ol’ hug and huge thank you for helping us squash those bugs! Now children are less likely to run headfirst into danger and bestowers will get the heck outta there if they’re breathing in poisonous gas. We also added a few tools to help out our modders and community translators do their thing. The changelog is below to read over.

If you want to keep playing on the previous version of 1.4, you can use the Steam beta branch “version-1.4.3563”. To do this, r-click RimWorld in the Steam library, go to properties, open the betas tab, and select the version from the dropdown.

2022 was a wild and fantastic year for us at Ludeon Studios. We released RimWorld’s third expansion, Biotech, which brought babies and children, new mechanoids, the mechanitor, gene modding, and xenotypes to the game. We ran several Steam Deck betas and became verified – now people can play RimWorld anywhere, anytime! Our team grew in size with several incredibly talented individuals at the helm. Who knows what we’ll get up to in 2023.

The RimWorld community has been with us at every step, and your voices make a difference and actually shape the game. So keep talking to us in the Discord! Please continue to share your feedback and fanart and memes and screenshots and videos and mods and edits with us. We love your creativity and I’m regularly blown away by what people make and do in RimWorld.

You can find us at the official RimWorld development Discord where we test and submit bugs, on the RimWorld subreddit, or at the Ludeon Studios twitter.

Mushy gushy feelings aside… I wish everyone a wonderful holiday season and an excellent start to your 2023! See you guys next year, haahaaah…
