Upgrade issue from 1.0.5 > 1.0.7a

[eonic]

I have been updating about 50 B-Team servers today and one issue I have noticed is from 1.0.5 > 1.0.7a where I get the following crash.

You can find all of it on http://pastebin.com/DXkq0fZG

 

It seems to be a problem with the Biomes'O'Plenty chunk generation.

I was considering it may be an issue with the MCPC+ build 235

Has anyone else had this upgrade issue and know of a possible fix?

I have not had biome issues, but there is also an issue with dragon mounts crashing the clients.  r34 is bugged and fixed.  It needs to be patched to r35.

I seem to have solved this , it is always the case when you start a post.

I have installed MCPC-Plus-164-235 when the server was using the default forge before I upgraded.

As soon as I restored the original forge the server booted ok...

 

A word to the wise, make a backup of the server files before you make the upgrade… at least you can quickly go back if it all bugs out on you.

 

Now to try a previous version of MCPC+ to see if there was not a conflict.

 

Thanks @demfels, thats was interesting to know.
