Minecraft ver: 1.21.5
Fabric ver: 0.16.4
Puffish Attributes ver: 0.7.4
Default Skill Trees ver: 1.1
Mod ver: 0.16.0 & 0.16.1 (After discovering the bug I updated the mod but it didn't work.)

Player could take all kinds of damage normally at the beginning, but as time went by and I leveled up my skill tree, the player became immune to falling damage.

Falling on a block cannot make sound either, only falling particles appear.
Executing "./gamerule fallDamage true" does not work.

Can confirm the issue not caused by other mods.
ps. I installed "Stronger Skill Tree for pufferfish's skills"(ver 1.0) but seemingly not its fault.

if u need any more information(log, pic, vid, etc.) plz reply. Sorry for disturbing.

Thanks for reporting. This issue is caused by the Attributes mod, 和 now it has been fixed in version 0.7.5.

Thanks！！！！
