# 👾 New Mod Update 👾
## 🐛 Bug Fixes
* Fixed hopper minecarts crashing with `IndexOutOfBoundsException` from a race in Lithium's shared entity-movement trackers
* Fixed hoppers crashing with `IllegalClassLoadError` from a mixin-package helper class being referenced directly in Lithium's entity-movement trackers
* Fixed a race between async mob spawning and scoreboard team assignment that could desync a player's team and kick them (Incendium)
* Fixed piglins and other mobs crashing the server with `NoClassDefFoundError` when the nearest-item, nearest-living-entity and nearest-player sensors ticked
* Fixed server deadlocks between the tick pool and the server thread during entity locking and off-thread chunk loading
* Fixed a race in `ServerLevel#tickChunk` over the shared random state when async random ticks are enabled
* Fixed a lock-order deadlock between chunk section locks and Lithium's entity-movement tracking locks that could freeze or kick clients
* Fixed an `IndexOutOfBoundsException` race in Lithium's block-change tracker
* Fixed a lock-order-inversion deadlock in Lithium's block-change tracker
* Fixed an `IllegalClassLoadError` in Lithium's block-change tracker
* Fixed a chunk-wait contention timeout that could stall the tick thread
* Fixed an `ItemEntityList` concurrency race in Lithium's item stacking
* Fixed the crash when re-entering a chunk full of hopper minecarts through a nether portal: minecarts are now always ticked on the main thread
## ⚡ Changes
* Marked Accelerated Recoiling as an incompatible mod: it keeps single-threaded entity-collision state that parallel ticking corrupts, which spammed `IllegalStateException: Unbalanced section view release`
