Vector plates stops when no player is around even when the chunk is loaded.

Here is the setup, when i leave the area coal blocks will pile up in front of the dropper, when i return its starts moving again and a big pile of coal will start go around. The hole setup is within one chunk.

Minecraft: 1.10.2
Forge: 2185
Server: Yes
Chunkloaded: Yes, with EnderIO chunkloading wards. PowerGrid 360/500

This is a very interesting issue that I have not been able to reproduce. Do you have any further information about this?
