Does the issue occur in the editor or during gameplay?
Gameplay
If it's a gameplay issue, please specify which movement system and camera type you're using (free movement vs. grid movement, third-person vs. first-person) or N/A if not applicable:
Free movement and third-person camera. This bug doesn't exist on grid-movement
Briefly describe the issue you're experiencing:
This only occurs in "Free Movement". Simply, set up 2 separate walking animations. For ex: Walk and New_Walk. Override the walk to New_Walk via script in the game. For ex: Make a clickable object that executes the override script. The new walk animation starts to play but only the first frame plays. Again, this problem doesn't exist on grid-movement. Slayer confirmed the existence of this bug too. Here is a video recording of the bug. In the video, the script is executed when the player equips a giant hammer. The script that overrides the animation is tied to the "on equip script" part of the hammer item. (Note: before this report, I made sure that the bug was not related to anything else in my project. I re did the animations, restarted the engine, checked the scripts, and asked Slayer to check the scripts too and he kindly looked into the scripts. No problem in my project might cause this bug.)
Are there any errors in the in-game debug console or external console window?
There are no errors when the animation change happens.
Provide the steps necessary to reproduce the issue:
Simply, set up 2 separate walking animations. For ex: Walk and New_Walk. Override the walk to New_Walk via script in the game. For ex: Make a clickable object that executes the override script or make an item that triggers the script as I did. The new walk animation starts to play but only the first frame plays.
Provide a download link to the bare bones project (strongly recommended if it's an in-game issue, since this helps significantly when attempting to reproduce it; the report will also be given more priority in this case):
I posted a video of this bug happening. That's the best i can do.
NOTE / UPDATE: The same bug happens for the sprint animation too. However, the idle animation override is fine. So far, walk and sprint in free movement are broken when you override them via script.
