I don't want to release these as finished mods, since they muck about with important parts of RimWorld's inner workings, and I have not given them particularly thorough testing. But I also know that these issues are seriously affecting some players' gameplay, so I want to put them out there for the people who are willing to accept some risk to try to find fixes."World" pawns are pawns that are kept around in the background, and simulated, tracked so that you can experience things like raiders coming back in later raids, or keep your colonist's family members in existence when they aren't on the map. A lot of them can build up over time; in a large, old colony they can easily make up 50% of the time taken to calculate each tick. When traveling on the world, with out any active colony maps, it can be 90% or more. This mod implements a garbage collector for world pawns. It looks over all of the world pawns, figures out which ones are related to "important" pawns (e.g. your colonists), and throws away the rest.I suspect that this mod will have a larger impact over time than it will immediately after it is installed. Additionally, it will be able to delete more pawns if you butcher/incinerate raider corpses rather than having large graveyards.Each time a map is created & destroyed (e.g. during faction base raids), RimWorld leaks quite a bit of memory. This mod fixes one of the main causes and significantly mitigates another (unfortunately not fixed because I cannot for the life of me figure out how it is happening).This will probably reduce or eliminate memory leaks and will probably not break anything. I think. (Note that this a test update to Zhentar's Vanilla Fixes , so it also includes the other fixes in there)
