To Reproduce
Steps to reproduce the crash:

1. Get into a world with both the latest Flan's Mod and MalisisCore installed.
2. Place any tank.
3. Load it with any compatible shell.
4. Fire the main gun (you may find that the shell will explode upon leaving the tank's barrel, which is another issue with the incompatibility; to avoid this, either aim your gun higher or break and replace the vehicle).

After following these steps, the game should freeze around 4-5 seconds after firing the shell.

Additional context
When firing tank or aircraft guns while MalisisCore is installed, the game will freeze, requiring a forced shut down, producing a crash report detailing a StackOverflowError due to the ray tracing class(es). The fix released in Beta8 did not fix this issue; the crash still occurs with this version.

@ChrisLane

I just tried a build with your change implemented. The crash is indeed fixed, however tanks shells still explode right outside the tank's barrel. Unlike in other builds, however, this cannot be avoided by simply aiming higher.

All other guns, including tank machine guns, work just fine though.
