Whenever I log off in area with certain rail craft tank then I restart my client I get this error.  It will go away if log into a different part of the server (x,Y,Z, POS change in players folder). Strange thign is that it only happens in a certain chunk area and only if I have resrtared my client in that area.

 

I posted on Railcrafts Forums and ConvertJaguar told me to re post here.  Not sure if you will update the older version of forge past 738 for 1.5.2 though. But Just wanted to keep you guys informed as most people are running 1.5.2 on servers i assume right now.

We dont update older versions. But this looks more like the entity isnt registered or something.

And looking at those files, I'd say Forge is not the only jar mod you have intalled.. May wanna look into that.
