Code:
movss xmm1, [ecx+0x18]
Looks as:
Code:
CNavLadder -> m_length
It's UAF (Ladder is destoroyed by somebody) or something overwrite that region of memory by mistake.
I think CNavLadder pointer is also broken.

Patch can be done by verify CNavLadder against all known pointers if there is some way to retrieve them.

Also, can't found server.dll + 0x3fcbff

yzybb, can you send your "\left4dead2\bin\server.dll" file?
