It conflicts with some other plugin that uses SDKHooks, but I'm not sure which. Whatever plugin it is, it messes with the direction they bounce.
To test, I unloaded SDKHooks (and therefore all SDKHooks-using plugins), reloaded SDKHooks, then loaded only rocketbounce, it worked fine. refreshed all plugins, it got all buggy again.

It's not homingrocket, because I unloaded that and it still did the off-angle bounces and straight-on-shot exploding. It *might* be holyarrows, but I'm not sure.

Will continue testing later.

If you want the version that bounces off the walls, go into the source, look for "other < 1 || other > MaxClients", change that to "other != 0".
