Unusual animal size-variance on Paper server

[sverinn]

CraftBook Version

5.0.0-SNAPSHOT+4863-9cb04b6

Platform Version

Paper version 1.21.1-16-master@bf5852a (2024-08-16T07:29:16Z) (Implementing API version 1.21.1-R0.1-SNAPSHOT)

Confirmations

• I am using the most recent Minecraft release.
• I am using a version of WorldEdit compatible with my Minecraft version.
• I am using a version of CraftBook compatible with my Minecraft version.
• I am using the latest or recommended version of my platform software.
• I am NOT using a hybrid server, e.g. a server that combines Bukkit and Forge. Examples include Arclight, Mohist, and Cardboard.
• I am NOT using a fork of WorldEdit, such as FastAsyncWorldEdit (FAWE) or AsyncWorldEdit (AWE)

Bug Description

Animals suddenly became gigantic or miniature - possibly because of animal scale variance applied by CraftBook5 retroactively/incorrectly?

Expected Behavior

Normal-sized animals with scale variance

Reproduction Steps

1. Start a paper server and generate a world
2. Stop the server
3. Add CraftBook5 plugin
4. Start the server and let it run for some time
5. Animals spawned naturally now occasionally have scale from very small (<0.25x of original) to very large (>2.5x of original).

Anything Else?

No response

what is in your BetterAI config? the only way for this kind of thing to happen is either if it’s configured to have extreme variances, or something else on the server had already applied variance multipliers that are multiplying the ones set by craftbook

Also, checking entity data revealed this:

Modifiers go on for about 100 lines or so

It seems that the older the entity is, the more repeated modifiers there are. For an entity 37500 ticks old there are 11 modifiers, an entity 925000 ticks old has 40-50 of them. Although, I'm not sure there is a correlation since I've been able to find 100000 ticks old entities with hundreds of modifiers.

I can 100% confirm this is CraftBook related since only entities listed for variance in config are affected.

The modifiers in your screenshot are not the ones added by CraftBook, it uses a size_variance and size_variance_breeding tag, such as can be seen in this video- https://x.com/the_me4502/status/1800491075884478902?s=46&t=9fkuzVwR2af-no0wwGig9g

if the tag is initially being added by CraftBook, then something else is merging that data into the generic scale tag and removing CraftBook’s tag- hence why it’d be getting added multiple times
