I downloaded Lucky Blocks and wanted to play them with a friend in a Minecraft Lan world via Hamachi. Since then, Minecraft has always crashed when one of us opens our inventory in creative mode. Or it also happens that the other person can't see the lucky blocks at all.
You must all have the mod installed, otherwise it is clear that one of the blocks can't see. In the crash logs you can see where the problem is.
Both have installed the lucky blocks in the crash log only error code -1 Internet did not help either
There will certainly be more than error code -1 … There's usually a JavaException with the entire StackTrace.
I'll look again
Java.util.ConcurrentModificationException that was in the log
Exception in server tick loop
Then you've already come to the right place. Can you still send the rest of the exception? So it looks something like this
java.util.ConcurrentModificationException
As expected, the problem does not come from LuckyBlocks but from PotionCore. Look here:
at com.tmtravlr.potioncore.PotionCoreHelper.clearNegativeEffects (PotionCoreHelper.java:232)
at com.tmtravlr.potioncore.PotionCoreEventHandler.onWorldTick (PotionCoreEventHandler.java:555)
And what should I do now
I also found this one, I don't know who the right one is:
java.util.ConcurrentModificationException
at java.util.ArrayList $ Itr.checkForComodification (ArrayList.java:901)
at java.util.ArrayList $ Itr.next (ArrayList.java:851)
at com.tmtravlr.potioncore.PotionCoreEventHandler.onWorldTick (PotionCoreEventHandler.java:554)

Both exceptions are triggered by PotionCore. You have no choice but to take out the mod or try a different version that may solve the problem… Unfortunately I can't help you with that anymore
Nevertheless many thanks. Just lucky blocks without Potion Core will be difficult
But in the single player world everything works
