FAIL!! Iam said of IC2, not MCPC. Repeat: Any of mod function normal, the IC2 give me problems!
Please be a bit more polite.
Anyways, as we have said on your post, these functionalities work perfectly fine on Forge servers, but in your case it does not work on MCPC+ servers. Hence, it must be an MCPC+ problem. This is because IC2 doesn't support (and will not in the near future) MCPC+ or Bukkit, so your best solution is to get a port.
Although we might be able to solve them if you give us the logs.
On a final note, please avoid hijacking other people's threads.
