Describe the bug
There really isn't any way to replicate it that I know of, but basically what is happening is babies and toddlers will reach max age then reset to the lowest point, so for babies back to 24:00 and toddlers whatever the starting time is.

Version
7.5.5, 1.20.1, Curseforge

How do you notice that reset?

I notice they get bigger and then revert back to toddler form, or for babies, I notice what time the timer is on them then I notice later on, the time has reset

I need a way to reconstruct, please share everything: server type, mod loader etc. Did you try without any other mods?

Thanks for the pack!

In the original post you said curseforge, which is not a loader.

When it comes to mod loader-type stuff, I had that included in the initial post. The server is a desktop forge server. Also, no I have yet to try it without any other mods to see if this issue still arises... here is the mod pack if that's helpful in any way.
