Or manually resolve the conflicts, it's not that hard
server not have config for RS
for example - conflict with advanced machines mod, compressor show me fusion reactor interface, extractor - autominer, macerator- isotopic separator, but working properly
instead of rubber sapling on forestry farm grows nuclear warheads
1. Autominer locator not working in SMP 
2. I'm download 84b server and client, but console (server and client) shows that i use version 81 
3. Craft table doesn't show item recipe picture 
4. No description with the object name 
5. Too more ID conflicts with forestry mod
server updated normally, but client, after update, crashed
