Issue Description

While this mod and twilight forest are both installed. It seems that Winter Wolves are broken when they attempt to spawn.

If I try to find these broken Winter Wolves spawning naturally in the twilight forest's Snowy Forest Biome, the game instead may not even spawn them. Or even worse, crash the game. Since it's trying to spawn an invalid/broken entity. (I can't find the crash log for that one since it's buried deep into my other debugged crashes)

I've tried submitting a issue report to the twilight forest issue tracker, but got no response to them: TeamTwilight/twilightforest#455

Relevant Mods

Twilight Forest - MC 1.12.2 - 3.7.424 (latest version)

Reproduction Steps

Steps to reproduce the behavior:

1 - Spawning Winter Wolf via spawn eggs

1. Be in Creative mode.
2. Get a Winter Wolf egg from the creative menu.
3. Use the Winter Wolf spawn egg.
4. It won't spawn anything. (error: https://pastebin.com/JzjxRVD2)

2 - Now, this second part CAN be skipped, since the first one already explains the issue anyways. (So, you can do this if you want, but I suggest you don't, since this one takes a while)

1. Be in Creative mode. (If you want)
2. Enter the twilight forest.
3. Find a Snowy Forest Biome.
4. Winter Wolves were either likely won't spawn or crash the game.

Expected Behavior

I've expected the Winter Wolf from twilight forest to spawn normally and behave normally with this installed.

Actual Behavior

Winter Wolves won't spawn via spawn eggs or natural. And instead give out a "Duplicate id value for 18" The same error I've posted above: https://pastebin.com/JzjxRVD2
