Okay so I have all the major mods (Redpower2, Buildcraft 2.x, Industrilcraft2, Railcraft, Equivelant Exchange etc)

 

To make my life easier as a server owner, i manually assigned all my block ID's nicely in the extra block ID space

 

Before forge had the 4096 on my server we were still playing with the old ID's and not using any 4096 fix as we would have to start a new map. Then came forge with the 4096 fix and we thought, yes lets do it, and start a new map. So i load all my custom set ID's and a new map

 

A few hours in my friend attempts to place a coke oven brick from railcraft and crashes

finding this odd i start testing it out, and with the other mods

Well what did i know, when we grew rubber trees from IC2 we would crash, when we placed any of the microblocks from redpower we would crash

 

So I stripped out everything from my server an loaded up just redpower and still we crash

 

I moved the ID's back into the 0-255 range, and didn't crash.

 

I can conclude that there is a problem with tile entities and the 4096 fix in forge when using SMP

 

At no time does the server crash it is perfectly fine, blocks are places when we log in

 

Here's a crash log from what is happening, with the list of mods loaded

Your client/server IDs are out of sync.

Updating to forge 151 has fixed this

thankyou for the fix lex
