Calling engineFreeModel right after destroying custom content causes crash

[ffsPLASMA]

Describe the bug

When calling engineFreeModel right after destroying custom loaded content associated with that ID causes following crash:

Version = 1.6-release-22388.0.000
Time = Thu May 9 19:24:39 2024
Module = C:\Program Files (x86)\MTA San Andreas 1.6\mods\deathmatch\client.dll
Code = 0xC0000005
Offset = 0x0002C089

EAX=00000000 EBX=330CE040 ECX=00000000 EDX=000066CC ESI=4DAB0268
EDI=5946E5A0 EBP=0177F930 ESP=0177F914 EIP=58A2C089 FLG=00210246
CS=0023 DS=002B SS=002B ES=002B FS=0053 GS=002B

Steps to reproduce

1. request new ID, load custom TXD/DFF/COL to that ID
2. destroy the custom content elements, then call engineFreeModel

Example:

-- destory TXD/DFF/COL elements
for _, uCustomContent in pairs(tblContentCache) do
if(isElement(uCustomContent)) then
destroyElement(uCustomContent);
end
end

-- free ID
for _, iNewEngineID in pairs(tblModelNameToAllocatedID) do
engineFreeModel(iNewEngineID);
end

Version

Client: 1.6-release-22388.0.000

Additional context

There is a workarround I figured out. Simply putting a small timer between these two actions solves the crash.

-- destory TXD/DFF/COL elements
for _, uCustomContent in pairs(tblContentCache) do
if(isElement(uCustomContent)) then
destroyElement(uCustomContent);
end
end

-- small delay to fix crash
setTimer(function()
-- free ID
for _, iNewEngineID in pairs(tblModelNameToAllocatedID) do
engineFreeModel(iNewEngineID);
end
end, 10, 1);
