| Issue ID | Description | Patch Solution |
|----------|-------------|----------------|
| HK-4221 | SPU solver – memory overwrite in hkpSolverContact when > 256 contacts. | Added bounds checking; dynamic contact buffer reallocation. |
| HK-4225 | Multithreaded determinism failure – floating-point operation order changed per thread. | Enforced strict FPU rounding mode (hkMath::setRoundingMode) and deterministic reduction steps. |
| HK-4230 | CCD misses for thin capsules against fast-moving triangles. | Increased sweep refinement steps; added speculative contact caching. |
| HK-4233 | hkpWorld step crash when removing rigid body during collision callback. | Delayed removal queue; safe iteration guard. |
Before hunting down this decade-old relic, consider that the modding scene has evolved: havok sdk 2010 20r1 patched
For most modern mods, using the X64dbg debugger to patch game binaries at runtime is safer than redistributing an entire patched SDK. | Issue ID | Description | Patch Solution
