No profiler enabled, didn't see anything unusual, just got 'disconnected' from server in single player followed by a crash when tried to reenter world

java.lang.IllegalArgumentException: Tried to register duplicate PermissionNode 'spark.profiler'

It's heavily modded, so it could be an incompatibility, but I've played for hours before the game crashed...
