Patch 0.5.4 is out! This is the largest bug fix patch we have made for Mechanic Miner yet, with over 200 bugs squashed!

We would like to thank our community for their help with identifying the swarm of bugs - thank you so much for your feedback and suggestions!

Version 0.5.4 includes fixes to graphics particles, blocks and various parts misbehaving as well as a handful of collision errors crash fixes. It also includes quality of life improvements such as additional information in the load game menu, so that you will be warned if you try to load a manual save where a newer auto-save exists. These are just some of the changes, you can find the full list of patch notes below!

v.0.5.4 patch notes:

Changes:

• Reduced the cooldown of the Demon Interceptors phasing ability.
• Choosing the Respawn at checkpoint option in the menu will now display a confirmation box.
• Added information in the load game menu showing if the player is about to load a game that has a newer autosave.
