invisible player and hard lag when opening identity menu

[WerewolfBX13]

When I open the menu it shows every single mob that is in the game at once (my modpack prolly has 300+ mobs) and causes bunch of a lag - It would be better if it has pages instead or trying to render everything at once.

The real issue is my player gets invisible when I select a mob (prolly cuz it takes too long to render it all) and game crashes when player dies while using mob skin.

Is it supossed to happen?.
