Bug Report

Last night everything seemed to be working fine, but now trying to play again, every time I go to "SinglePlayer" then select my world and click "Play" and it starts loading, after ~30 seconds or so it notes that it's "Shutting down internal server" then closes the game out and gives me a crash report. This happens every time, and even when attempted to load slightly earlier backups.

Expected Behaviour

I should be able to load and play my world normally.

Possible Solution

The first bunch of entries in the crash report are all things like:

java.lang.NullPointerException: Unexpected error at hellfirepvp.astralsorcery.common.constellation.perk.PerkLevelManager.resolveLevelCap(PerkLevelManager.java:110)

so it makes me think it's related to the Astral Sorcery perk system?

This makes sense because last night is when I unlocked the Astral Sorcery perk system for the first time, in Age 2. Additionally, while I picked the attunement which levels up by placing blocks first, I noticed that it leveled up extremely slowly, taking quite a while to just get halfway up level 1, so I crafted & used a "Shifting Star" item to swap my attunement to 'Vicio," which levels up by moving instead. Suddenly I was gaining whole attunement levels just from walking from one side of my base to the other (I had on Wild Dog boots, lots of Dirt Paths, and a few 5x Horse Totems around, so I run at a decent speed I guess). After a half hour or so of just moving around my base and fiddling with more Astral Sorcery stuff, I was at attunement level 14, which seems ridiculously quick given how slowly I was leveling up with the old constellation. Perhaps this is related to my current crash? I continued playing for another few hours after this without noticing any problems, it is only now when trying to load the world that it crashes.

Steps to Reproduce (for bugs)

Logs

• Client/Server Log: latest.log at https://gist.github.com/X3n0n3x/689efacb45e19859c458ab0b52b888d1
• Crash Log: crash-2019-05-01_13.14.29-client at https://pastebin.com/W9TCRfQN

Client Information

• Modpack Version: 3.1.1
• Java Version: Java v1.8.0.181 (64 bit)
• Launcher Used: Twitch, with JAR Launcher
• Memory Allocated: 8192 MB
• Server/LAN/Single Player: Singleplayer
• Optifine Installed: No
• Shaders Enabled: No

World Information

• Modpack Version world created in: 3.0.8 (I updated to v3.1.1 at the very end of Age 1, just before advancing to Age 2)

• Additional Content Installed: No other mods, but I disabled "SmoothFonts" via Twitch profile options for performance, and am also using these "Additional Arguments" in Twitch Launcher:
  -XX:+UseG1GC -Dsun.rmi.dgc.server.gcInterval=2147483646 -XX:+UnlockExperimentalVMOptions -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M

UPDATE:

Apparently this problem has happened to others, and supposedly was fixed in v1.12.2-1.10.12, so I will attempt updating Astral Sorcery to v1.12.2-1.10.17 using the Twitch "update" button in the "installed Mods" list for Sevtech, and we'll see what happens.

EDIT:

So I updated and so far so good, seems to be working, thanks for the suggestion! I did get a crash-to-desktop when using "Save and Quit to Menu" pause menu option, but otherwise the game loads up and runs now.

However, simply walking around in my base still seems to give me attunement level experience at a crazy high rate. Does anyone know whether this is working as intended, or just something I can bandaid over by adjusting the settings in the astralsorcery.cfg file?
