Description of the issue:

When firing the railgun on a multiplayer server, the server immediately crashes the moment the projectile is launched. I tried replicating this in singleplayer in the same modpack, but it didn't cause a crash there. I also tried an instance with just IE, and it didn't cause a crash in singleplayer either. The issue is multiplayer-only and is the only instance of the server crashing this way that I've seen this far.
