Patch Notes: Early Access (EXPERIMENTAL) - v0.3.4.0 – Build 119583. This patch was released on April 15, 2020.

The original post can be viewed on Satisfactory's Discord and Reddit.


Hi Pioneers!

We are doing a little update to Experimental with a bunch of fixes and improvements. A new feature we are introducing with this update is Multiple Hotbars! You will be able to switch Hotbars with the arrow keys by default (those standard bindings are likely to change in the future) and fill up a total of 10 Hotbars.

It took a while longer than it should have, but the fluid capacity of Trains and the Buffers is also increased. They should no longer be trash, thanks for reminding us Kibitz. Sorry to everyone that has been waiting for this.

Something to note for this version is that we dropped support for saves that have not been played since before Early Access started. That means saves from the Alpha and the weekend before release. If you have a save that started at that time but has been saved after Early Access has released this will not affect you. Remember that it’s always good to BACK UP YOUR SAVES just for safety. We could have messed something up.

Apart from this there are a lot of small but sweet improvements and potentially a good number of new bugs. Check out the patch notes below for the improvements and let us know about whatever bugs you find on the questions site.

Hope you all have a good time with the patch! <3

PS: If you are playing multiplayer you will see some placeholder UI in the join menu when you are connecting to your friends. You can ignore that, we are just trying some stuff out.
