bug

hello, annually I created a serve nukkit and soon after creating it I tested the vanilla items to see if it was working normally, when I tried to use some RedStone items and none of them worked, the RedStone signal system does not work, what do I do?

Can anybody help me with a bug that came out on my minecraft server? I haven't install any plug-ins or so, tried to connect to it from my tablet and then the command console showed this: java.lang.NullPointerException: Cannot load from byte/boolean array because "this.skyLight" is null at...

I have just created a new Nukkit server for the first time and it's not allowing me to place signs, even with permission plugins (LuckPerms) removed. I'm not sure if it's a bug or I'm just a big idiot.

for some reason, everytime i die, i would respawn at spawn point, then immediatly be teleported ina bedrock, then fell in void, i already set a world spawn, and i removed some plugins, but still happens
