Crashed because of Deepslate Stairs

[Dandandooo]

I got a crash report that is attached. I am baffled, and I don't know if it could be the mods I'm using.

I'm aware of that. I never wrote that in a command, nor did anyone on my server since I am the only one with OP permissions. The server crashed on it's own.

@laxativedude This isn't the Forge forums, this page is only used for reporting Brigadier issues. Also, Mojang does not make Forge or mods.
