i keep getting this in my crashlog when starting minecraft (1.16.5 fabric)

[11:43:39] [ForkJoinPool-1-worker-1/WARN]: The mod "cardinal-components-entity" contains invalid entries in its mod json:

• Unsupported root entry "side" at line 8 column 11
  [11:43:39] [ForkJoinPool-1-worker-5/WARN]: The mod "cardinal-components-base" contains invalid entries in its mod json:
• Unsupported root entry "side" at line 8 column 11

please fix this...

then why do those things dissapear when i remove polymorph

Are you serious? It's not a Polymorph issue...

because its a cardinal components issue lmfao Polymorph just uses its API. and also, that warning does not affect anything

I'm not sure if this was really erroneous or due to an outdated CCA or something, but I've updated the 1.16.5 Polymorph version's dependencies in the latest update which should rule out anything on Polymorph's side regarding this.
