Hello Scientists 🙋‍♂️

🛠️ We’re constantly improving Monster Lab Simulator, and a new content update is on its way. We’re planning to share a devlog in the next days. You can find the changes in this hotfix below:

Improvements;

  • Robot Helper keeps up the hard work! It can now carry three objects at the same time, helping you organize your lab better than ever.

  • Orb Vending machine is now freely moveable!

  • Added a new sound effect for order tube.

  • Daily Experiments and Weekly Protocols are now being generated right after the tutorial completed. New players will no longer wait for a Day or a Week (in game) to pass.

  • Minor adjustments were made to the Furnace in the Starting Area: its depth was increased, the step in front was lowered, and the hatch was raised.

  • The orientations in the Refrigerator UNC-2000 for the Iron Skin Potion and Defensive Potion now match the rest of the potions.

  • Requested order rarities are now clearly being written in the order screens.

Bug Fixes;

  • Fixed a bug that prevented Bour, Bourat and Bournex from being defeated in battle. Naughty Bour is now properly tamed!

  • Fixed a bug where the player’s team always started battles at full health. Health values are now correctly carried over into battle.

  • Fixed an issue where the following achievements were not being completed properly: Nerimpossible, Gardener, Pure Elements, and Fulus on Fire.

  • Fixed an issue where radio wasn’t being effected by music volume.

  • Fixed a bug where an empty quest titled “To pick up an item, press LMB” could spawn. This has been resolved and will no longer occur.

  • Monster Lab Simulator is still in development and players have found some hidden panels that are still under construction. These panels are now properly hidden until they’re ready!
