Summary:

Backwards compatibility of behavior pack animation controllers broken

Impact:

Server-side animation controllers not working can make many maps, including Hex Chunk Challenge and Dog Island, unplayable. 

Repro Steps:

1. Open Hex Chunk Challenge by Pixel Squared on the marketplace.
2. Note the content log error when approaching the floating village island (155 85 -99).
3. Note that the Block Processor (166 75 -92) on the island no longer functions.

 

1. Open Dog Island by Pixel Squared on the marketplace.
2. Note the content log error that immediately appears.

Observed Results:

The Block Processor does not function due to broken backwards compatibility.

Expected Results:

The Block processor functions as it did when it was created, preserving backwards compatibility.
