CobbleOptimizer 4.1.2
All Cobblemon patches are now disabled by default. The patches introduced in 4.0.0 (thread safety fixes, bugfixes, caches) were causing ghost Pokemon entities for some users. They are now fully configurable and off by default.
If you were experiencing ghost Pokemon, simply updating to this version will fix it — no config changes needed.
Changes:
- All 13 Cobblemon patches (thread safety, bugfixes, caches) are now disabled by default
- Each patch can be individually toggled in the [patches] section of cobbleoptimizer.toml
- The core optimization features (tick throttle, AI freeze, adaptive spawn, batch despawn, emergency mode) are unaffected and remain enabled by default
Note: If you're upgrading from 4.1.1 or earlier, delete your old cobbleoptimizer.toml so the new defaults are generated. Otherwise your existing config will keep the old true values.
