A world save doesn't work once the modpack get updated (Industrial Age The Turning)

[_Mohandar_]

I had 2 saves in my folder, one map was empty, and one with alot of stuff built in...

The problem is that when I uploaded this modpack from version 9.2.6.0  to 9.3.5.0  noone of the singleplayer world works anymore, and this is weird because the changes aren't so enormous.. rather, the changes are few, but when I try to load a world saved in 9.2.6.0 the screen of minecraft goes white and it stop like that ..forever? until I close java process manually.
As I mentioned the modpack is Industrial Age Enterprise The Turning http://www.technicpack.net/modpack/a-new-age-enterprise.55905

I think that what is really weird is that, the modpack creator has not this problem on his server-world, but as he said, singleplayer and servers works differently (?)
 

I can't update the file-log here because it's too heavy, 7000 kb   .... 

but you can download the zip from copy here https://copy.com/kHauvWtImlq0uJmV chek the "lastest log" in the bottom for the most I guess the problem is there (?)

here is where the map works and load in 9.2.6.0 https://copy.com/WXxobv8ZsN7o4OBB , just in case.. :/

I see no errors of any importance in any of the logs you provided. Unfortunately this is something that really needs to be addressed by Enterprise12 as he's the one that will know what the changes happened in the pack and what might cause issues.

He said to try to show this to you somehow, btw I'll ask back to him then o:
It's really weird anyway, normally modpacks says the "missing id object" from the mod that lack in the world you saved, and once you take notice of this the map load without those items.. here it just does not load, lol
