Mountme mechanic makes target armorstand disappear.

MM 5.4.0 28c6b0f1 || Paper 169 (1.20.1)

The mountme mechanic seems to work for mobs aside from an Armorstand. Not sure if this was intentional. Tried MIR, EIR, Children.

Script:

# Mob file:
Skills:
- mountme @EIR{r=5;limit=1;sort=NEAREST;delay=5} ~onSpawn

# Skills
Test:
  Type: Armor_Stand
  Display: 'Test'
  Options:
    Invisible: false
    Invincible: true

This was all I found aside from the inital spawn event: image
