I get a strange crash on exiting from a single player world. Removing Astral Sorcery, eliminates the crash in its entirety. It save and exits, but during the 'shutting the servers down screen' if you click M1, it makes Minecraft crash. And the most annoying part is that it doesn't generate a crashlog. So I wanted to isolate the problem, if this is a memory leak issue or some mod item ID conflict that causes a crash on exit.

Try with newest curse version of as

Still crashing on exit. Everything loads up and plays well but it ALWAYS crashes on exit.

Seems like a crash caused by gamestages & bookshelf not having compatible versions. Gamestages calls a method that doesn't exist in bookshelf. Did you make sure those libraries use compatible versions?

Updated gamestages and bookshelf. Hmm.. It's frankly bizarre how those two mods would cause a CTD only when astral is present. Well, I learned something knew today.

Check the library resource mods as they can break other mods not related. And how to use the server log for debugging. I'll go back over the unload log and see if the script cleans up.

Update eliminated unload crash, looks like something in those older library resources didn't agree with how astral unloaded. I was suffering this issue for months since December and was just waiting for some updates to see if was just that version.

Yup, server log confirms unload crash is gone. It's just a bunch of journeymap silliness now. Unload errors are minimal now.

if you click M1

What are you referring to with "M1" ?

While it might not specifically generate a dedicated crash log file, is there anything in the log about it? Mind attaching one on that instance?

M1=Mouse button 1

when you click, the crash completes otherwise it just hangs and freezes until you click.

Edit: Use gist for that kind of stuff please.

Here is the end of the log when it begins to unload, attaching the actual txt file isn't working for some reason.

It's frankly bizarre as the crash only happens when Astral is in the loadout.

Alright. AS just has interactions with gamestages in connection to perk level caps per gamestage. So upon saving player-related data, it'd cause this to show up during integrated-server shutdown.
