0.9.30 potential issue?

[gilescope]

I'm just testing the 0.9.30 / 9300 draft build and seem to be getting some decode issues with getting the event state in polkadot-js

Unable to decode storage system.events:: createType(Vec<FrameSystemEventRecord>):: decodeU8a: failed at 0x000000000748accc420100020000… (index 1/2): {"phase":"FrameSystemPhase","event":"Event","topics":"Vec<H256>"}:: decodeU8a: failed at 0x48accc420100020000… on event (index 1/3): {"index":"EventId","data":"Null"}:: findMetaEvent: Unable to find Event with index [72, 172]/[72,172]

Here's the main stack trace:

Should I try main / is there a branch I can try? or do we think the issue is further down the stack?
