[porisius]

Likely the uWS thread not getting properly destroyed when the world is "destroyed" prior to reloading a new world from the reloaded save.

That's just my guess. I might need to reach out to some more experienced modders for assistance. I got an idea i can try though in the morning.

Another crash when the savegame reload is:

I apologize for not getting to this, but life is being, well, life... busy.

Could you do me a favor and drop back to version 1.4.2 please? The only loss will be the API getCrateInv and getExplorers being back on the game thread which I wouldn't think you would have too many to worry about.

I am curious if I did something funky with the repo that is causing problems, or if there is something else.

[hood-ok]

No problems. Switched back. I think the first crash in the initial message was at 1.4.2 actually. I encountered it multiple times and only then started reporting crashes.
For context, I have a service that fetches many endpoints asynchronously in short periods. This crash happens almost every time on game save reload. Less often happens when I exit to the main menu before loading the save. Probably the fetch happens at a very early time when the HTTP server has already started but the world is not ready due to a large save file
