Lava/Fire doesn't damage the player in Adventurer's Dream

Partner Rank: 4

Partner Team Reporting: Noxcrew

Verification builds: 1.9.0.5_beta_9-4_rc1

Summary:

Lava/Fire doesn't damage the player in Adventurer's Dream. This is not a bug with the vanilla version of the game. We did not do anything special with the lava in Adventurer's Dream that could impact this happening. DestructoBot 5000, which was created and converted around the same time (definitely in the same MC version) does not have this same issue. Mobs and items are still damaged properly.

Impact:

Very low impact. Players would expect to die if falling in lava during a playthrough, but will live. This doesn't ruin the experience of the map, but it should still be fixed sometime.

Repro Steps:

1. Load Adventurer's Dream by Noxcrew from the store
2. /tp -836 97 337

Observed Results:

You get a nice warm lava bath.

Expected Results:

You die in a fiery inferno bath.

Regression Builds:

We tried every build we had access to back to 1.2, and couldn't find a regression build. We were being blocked by spam asserts in those versions so we couldn't proceed to a point where we actually found a regression build.

Notes:

How did we not catch this for like a year...
