Hi,
This is a known limitation of NetDeltaSerialize, and it does understandably make it difficult to use this in most contexts. The custom delta serialization path is almost entirely used for fast array serialization now, and so we don’t generally recommend using custom delta serialization outside of fast arrays.
For more info, you can check out this related thread: [Content removed]
If you have any more questions, please don’t hesitate to reach out, but please note that support will be limited for the next two weeks due to the company break.
Thanks,
Alex
