I'd really love to say it's the last patch before 1.1, but I simply can't. There still is one more, seemingly random issue that can occur during a certain procedure but yeah... It's RANDOM. So random I had absolutely no luck with reproducing it for about an hour.

Structures:
-Pillagers Town - introduced a potential temporary fix for a certain scenario randomly not executing fully

Releasing update 1.0.5 to address an issue where most of the CONFIG options wouldn't save properly. Hopefully it's the last patch before 1.1.

Config:
-All of the options are now saved properly
-Resources check does not instantly apply when enabled in config if already been passed during a session.

Algorithms:
-Loading - fixed one-time procedure applying for each world load
-Hard reload - fixed procedure executing multiple times after one click

Version 1.1 is still in works and will be released for upcoming Minecraft: Java Edition 1.19.4. Meanwhile here is another small patch to address some of the worst issues present in previous build.

Mobs:
-Grand Illusioner - fixed bugs
-Grand Illusioner - rebalanced some parts of the fight
-Grand Illusioner - added missing notifications
-Witch - is now omitted when checking for mobs in a certain scenario

Structures:
-Pillagers Town - changed searching radius for a certain scenario
