→ The game crash

Also in the game output it spam this error :

Couldn't load protochunk java.lang.IllegalArgumentException: The value 0 is not in the specified inclusive range of 1 to 32 at org.apache.commons.lang3.Validate.inclusiveBetween(Validate.java:1032) at xd.<init>(SourceFile:19) at bnq.a(SourceFile:177) at bnv.a(SourceFile:680) at bnv.b(SourceFile:592) at bnv.b(SourceFile:213) at bnv.b(SourceFile:165) at tx.a(SourceFile:59) at tx$$Lambda$1562/254858450.apply(Unknown Source) at it.unimi.dsi.fastutil.longs.Long2ObjectOpenHashMap.computeIfAbsent(Long2ObjectOpenHashMap.java:479) at tx.a(SourceFile:54) at tx.a(SourceFile:25) at acu.b(SourceFile:80) at acu.a(SourceFile:61) at acu$$Lambda$1558/926738298.get(Unknown Source) at java.util.concurrent.CompletableFuture$AsyncSupply.run(CompletableFuture.java:1582) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745)
