AncientWarfare2 version: 2.7.0.704
Minecraft version: 1.12.2

I have a rather small mod setup using Ancient Warfare 2, and noticed that when flying around in Creative Mode, eventually the chunks stop loading, mobs are frozen in place, and changing gamemodes no longer works. It takes a noticeable amount of time before this is fixed, and can be rather painful to go through before I can even do anything. Additionally, trying to exit the save causes the game to hang and use a tremendous amount of CPU processing time. The log never mentions AW2 by name, but does mention these specific mods as of now: PrimalCore, Electroblob's Wizardry, Astral Sorcery, Quark, LLibrary, Mystical World, Mowzie's Mobs and Ice & Fire. I have no idea what is specifically causing this, but seeing similar issues with chunk loading on older versions makes me think that something might still be up with the town logic or something similar. If this is any help, happened upon a Yeoman Farm when it started.

Addendum: Noticed a new update from 3 days ago. Will test with this new version and see if the problem is resolved. If so, I will add one more mod and test again, and then mark this as resolved.

Edit: Seems the problem still exists. Will update the mentioned mods if possible, and see if that helps.

Edit2: Updating did nothing. Removed AncientWarfare2 (version 2.7.0.772), will test if the problem is fixed.

Edit3: Nvm, not a problem with Ancient Warfare it seems. Closing issue for now.
