To prepare for the 1.0.0 (microbe stage completion) release, we are making a few smaller releases to get more player feedback on the changes we are making. The biggest changes in this release are that all the reported save loading issues should be fixed now. And the remaining MP calculation system is totally redone, again, which should now result in there not being any MP refund exploits. However, due to the tight release schedule there has not been much testing at all so please continue reporting any MP related problems. There's also of course new gameplay features like new patch events and map visuals as well as multiple auto-evo and balance improvements.
There won't be a devblog for this release due to the short release cycle, but a PU post will be published later today: https://www.revolutionarygamesstudio.com/progress-update-11-22-2025

Patch Notes
Reimplemented the MP calculation system (again)
Added player population visualization dots on the map
Added a few new patch event types that affect compound amounts
Amount of ammonia in patches now dynamically changes based on consumption and production
Switched Thermosynthesis to produce glucose rather than ATP directly
There's a different intro cutscene now when starting with the panspermia starting location
Added a new GUI error popup that opens when the game runs into an unhandled error to make sure players can more accurately report these and not continue playing for a while without realizing which can lead to very strange bug symptoms
Auto-evo can now evolve toxin upgrades and they have an impact on the calculation now
Auto-evo now takes reproduction cost into account
Implemented a simple cell division animation based on physics pushing the new cell out
Buffed hydregonosome by 20% to make it a good upgrade again
Increased auto-evo strength on the player species in all difficulties
Instant kill protection against damage is now a disableable difficulty option
Stopped the player death timer when engulfed if the player has stored toxin as the player might be able to escape thanks to it
Endosymbiosis GUI is now grouped based on whether the species are present in the current patch or not
Added a sound effect for binding mode so that it finally has a unique sound rather than sharing the engulf mode sound
Tweaked the engulfing sound to make it loop better
The pause menu is now a singleton and the Thriveopedia as well to reduce allocations on scene change which might help with the random scene load bug
Made global glaciation trigger slightly earlier
Improved the microbe AI handling of escaping damaging hydrogen sulfide
Partial mod support should be now usable, which had been broken since the Godot 4 upgrade. Harmony using mods don't work on Linux but they should work on Windows now.

Fixed distance checks being mathematically wrong in the terrain system and added sliding terrain around when it doesn't fit to result in much tighter packing being possible
