[2020] Memory leaks

Thank you for bringing this up! To be clear, by memory leaks do you mean that the server's memory usage keeps increasing? I'm not entirely sure why that would affect the clients' framerate, but I suppose these could be related. Something that might give us a bit more clues on what's causing this is if you'd enter the command "showperf" in the debug console (which can be accessed by pressing F3) and shared us a screenshot of the view.

Originally posted by Frank Horrigan: NPCs and AI are known to cause memory leaks.

I was not aware of this either, that's something we definitely need to investigate. Have you done some kind of profiling to pinpoint what's causing the memory leaks, or how do you know it's caused by the NPCs and AI? Or do you mean they cause performance issues in general, such as framerate drops?

Thank you for the extra info!

We are aware of certain issues in the AI and pathfinding logic in particular that are causing occasional frame drops, and are working on getting rid of those and optimizing the logic. I unfortunately can't give you an exact ETA on these, but hopefully the next hotfix will improve the situation!

These issues don't seem like memory leaks though: a memory leak is a specific kind of problem that causes a program to unnecessarily take up memory. It typically doesn't manifest as frame drops or lag, but can make the program eat up excessive amounts of memory and eventually crash if the memory runs out, which doesn't seem to be the case here.
