Improvements to Saves, Performance, Venus, and Other Bug Fixes

Hey Folks!

Update v0.15.1.2 is now available on Steam, and your clients should be updating shortly.

This is a feature update to our "Across the System" milestone, which includes a mix of performance improvements, Venus fixes, and other bug fixes.

Saves from v0.15.0.0 and later should work. Note that if you were experiencing issues in the older save, this patch may fix some, but others may persist depending on the cause.

Note: 📢 indicates changes inspired by community feedback!

One of the more insidious bugs fixed in this patch involves OKLG_SEC. A prisoner there would spawn without any limbs or containers, and this caused items spawned on them (which would sometimes accumulate due to collisions with the station) to bloat save files. Some OKLG_SEC.json files were 200MB!

This save fixes the prisoner, as well as the redundant way it stored items that caused bloat. Saving and then loading any affected games should see significant drops in save file size. (Plus, more generally, save files should be slightly smaller now.)

We also made several changes which reduced the amount of log spam the game generated, which should also help improve performance and reduce crashing. In one case, a log file crashed the game when it hit 2 million repeated entries due to a "thawing" NPC that walked onto the map.

And speaking of spam, the player's PDA Notes app will no longer be the playground of bored NPCs across the universe.

Some players noted that restoring items and extinguishing fires on stations caused faction drops, instead of increases. This turned out to be a sign error in the data, (and not disgruntled maintenance union workers, as some surmised) and has been fixed.

We noticed some players wishing that inventory was a bit snappier, especially when sorting through many containers in their possession. So we've tweaked opening inventories to be near-instantaneous when the item is in range.

Venus also had some updates and improvements.

First of all, we discovered that several robots spawned in the construction zone there had messed-up careers, portraits, and other stats. This led to issues like human faces in the MTT, robots with citizenship or illegal status, some robots without LEO training being ganked by the other robots. It was pretty chaotic!

Those issues have been fixed, plus the AI tweaked so that LEOs and robots chasing the player across maps will no longer bee-line to the player after emerging from transit. Now, if they don't have line of sight, they'll switch to searching.

Lastly, the Venus aerostats had their gravity restored, plus a little sunlight tweaking for better visuals.

A new variant of the Babak ship will now spawn in some places, jettisoning corpses should no longer delete dragged items too, ores and other items should once again fit in cargo nets. Plus, modders can now specify which star system and starting station New Game defaults to via the TXTDefaultStarSystem in loot.json.

It's a pretty juicy patch!

As always, there's plenty more for us to fix, change, and add! And we'll be continuing in roughly that order. In the meantime, let us know if this patch helps you out, as well as if it reveals new problems!

Best,
