Open Game crashes when loading save

Summary of the problem Game crashes when loading save

Pack Version 1.2.0

What is the bug? Every time I try to load my save game crashes with report (provided in ling). I have tried to google the solution (some threads suggested downgrade EnderIO version to older one - not sure how to do that without braking pack).

System information:
Ubuntu 16.04 64-bit
Total RAM 32GB, used for FTB launcher 20.75GB
java -version:
java version "1.8.0_101"
Java(TM) SE Runtime Environment (build 1.8.0_101-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)

Mod & Version Modpack version 1.2.0 (first appereance), then I tried in 1.2.1 and 1.1.4. No alteration to mods, only edited Psi config (allowed different level for brak-block spell)

Is it repeatable? Yes, crash happens every time I try to load up my save. If you are interested, I can upload the world-save for you.

Known Fix None, can't use the save. Din't try to play new game.

Go to MCEdit or some external tool program and remove the block at this coordinate

Block location: World: (451,72,-3)

MCEdit isn't working for me - crashes every time I try to load any kind of save (even vanila MC saves) - don't know why, error msg isn't useful for me. Do you know any other program for this job?
