HDA rebuild failure after setting instance settings #167

I'm following along with the Tombstone Hive workshop: https://vimeo.com/572629821 Building the tombstone, bringing it in to UE4 works well, and modifying HDA params on an instance works fine. If I rebuild or recook an instance that hasn't had it's parameters change, then reloading from the an updated HDA works correctly. However attempting to rebuild an instance that has attributes changed from their defaults fails with a Finished Cooking With Fatal Errors bad_rebuild

The only errors that show in the console are:

[2021.09.22-06.30.48:897][199]LogHoudiniEngine: HAPI Asynchronous Destruction Started for . AssetId = 2805
[2021.09.22-06.30.49:071][204]LogHoudiniEngine: HAPI Asynchronous Instantiation Started for tombstone5: Asset=Sop/tombstone, HoudiniAsset = 0xab59ff40

If I recook all from the Houdini Engine menu or Rebuild All I have had some update to the latest HDA, however most customized instances continue to fail.

OS version: Ubuntu20.04lts UE4 Version: 4.26.2-0+++UE4+Release-4.26 Houdini Version: 18.5.696 Nvidia: 460.91.03

If there is a way to get more detail on the error messages I'll happily add more details.
