I was already trying to find a solution to this on the forum, with only some topics having the same issue as me, but no fix was found.
This is going to be a pretty long post, so bear with me here.
I have a forked Animate LocalScript in my game (R6), and it seems to be completely filling up the 256 AnimationTrack limit for Animators:
I started seeing the warning in the error report tab a while ago, so I did some research. Turns out this warning only appears if you exceed 256 PLAYING animations, not LOADED animations. I made a simple script to catch that warning and print all playing animations:
local anim: Animator = script.Parent.Parent:WaitForChild("Humanoid"):WaitForChild("Animator")
function check()
if #anim:GetPlayingAnimationTracks() > 256 then
local tableString = ""
for _, val: AnimationTrack in anim:GetPlayingAnimationTracks() do
tableString ..= val.Animation.AnimationId..",\n"
end
warn("thats quite a lot of animations\n", tableString)
end
end
anim.AnimationPlayed:Connect(check)
I was met with this in the error report tab:
(The list goes on for a while)
The interesting thing here is that all of those are 1 animation, specifically this one, uploaded by Roblox:
There were more warnings, with more unique animations:
Some of these are made by me, but the important thing is: they are ALL played from the Animate script.
So I went out looking for any faults in the script, and ultimately found nothing. While I do use a forked version, from what I can tell, most of the functions are identical to the most up to date version.
My version completely removes the tool animations, and adds some extra functionality to the KeyframeReached function, as well as playing an extra Sprint animation. My game does not parent the player character to nil, or anywhere other than workspace for that matter.

The key differences are:
- Some extra declarations on the top, will explain below
- Tool animations completely removed
- Extra “sprint” animation in
animNames - function
keyFrameReachedFuncon line 229 includes extra if statement for footstep sounds - function
onRunningon line 283 includes extra if statement for playing the sprint animation - function
moveon line 379 includes extra if statement also for playing the sprint animation

DataUtil - Not really necessary to post here, but using function :GetLocalData() returns a table with a BoolValue named “Running”, which is used in some places in the Animate script.
Im currently unable to test with a completely default Animate script, since that would break my game. Not able to replicate this either. This never happened to me, and I dont think anyone has reported this bug to me either.
I know this is a long post, but this is a pretty big issue, and I cant find any solution. Help is much appreciated.
