Description

When use the forge to deploy contract, I noticed there is a panic in runtime. the source code in pallet aura.
the error message is "Slot must increase". source code as follows:

pallet aura function

fn on_initialize(_: BlockNumberFor<T>) -> Weight {
			if let Some(new_slot) = Self::current_slot_from_digests() {
				let current_slot = CurrentSlot::<T>::get();
				if T::AllowMultipleBlocksPerSlot::get() {
					assert!(current_slot <= new_slot, "Slot must not decrease");
				} else {
					assert!(current_slot < new_slot, "Slot must increase");
				}

The client get the request for raw transaction, then try to initialize the runtime.
The new_slot is equal current_slot in on_initialize in aura pallet.

If we AllowMultipleBlocksPerSlot in runtime configuration, then everything is fine.
Contract deployment with forge is OK.
