Game crashing on map start with vanilla resource/behavior packs

• Partner Rank: 1
• Partner Team Reporting: Nitric Concepts
• Verification Build: Build 3692779
• Summary:: "Millionaires Luxury Castle" which is currently released on the Marketplace, upon letting mobs spawn on the map, presumably with pigs and skeletons as errors often point to either of them. An assertion error would pop up. The map mentioned does not contain any resource/behavior packs so it is probable that the default packs caused the error.

• Impact: Potentially any map running default resource/behavior packs would encounter this issue when encountering pigs loading in the game. With custom resource/behavior packs without altering vanilla resources/behaviors would also be affected by this.

• Repro Steps:
  1. Load up Millionaires Luxury Castle
  2. Error message pops up, example provided in screenshots
  3. Game crashes.

• Repro Rate: 3/3

• Observed Results: The game crashed with error assert error:
  "Assertion failed: Molang-error:minecraft:pig | Error: accessing a variable that doesn't exist: variable.is_paperdoll
  Condition is false: false
  Function: DebugEndPoint::contentAssert in f:\darwinwork\238\s\handheld\src\common\debug\debugendpoint.cpp @ 119"

• Expected Results: The game does not crash.

• Screenshots/Videos attached:

• Regression Builds: 1.13

• Notes: Ran the map on public and release build for 1.14.30, when the game encounters pig/skeletons with public build, similar errors pop up in content log, but not causing crashes. Would cause crashes if running release builds. Pig/skeleton resources/behaviors were not altered at all either as no resource packs/behaviors packs are attached.
