[10.98] Monsters animations like Fire Elemental are not working

[GustavoContreiras]

Describe the bug Fire elemental don't change sprites. I don't know if this is related to idle animations or it's a different bug.

To Reproduce See a Fire Elemental on screen.

Expected behavior See it change from sprite one to sprite two to look like it's on fire.

Environment

1. Latest OTClient
2. Protocol 10.98
3. Windows 10
